Lisa Swain therapy scene visual language analysis - the 180 rule

We all (except Lisa apparently) knew it was coming: a Becky Swain mention in Lisa's first therapy session!

Yet while it wasn't a suprise for us as an audience, we still felt Lisa's shock in that moment. Let's look at how that was conveyed visually in the scene.

In this 10th July 2025 episode (directed by Merlyn Rice), we were treated to six whole minutes of Lisa in therapy. A goldmine! The scene we'll be looking at is the second of three that take place during the therapy session. As the scene opens, we're shown a number of close-ups (the clock, posters on the wall, the therapist writing notes, his potted plant) as Lisa casts her gaze around the room, frustrated and impatient following her decision to sit in silence.

We're then shown a wide shot of both characters sat in the room, to once again establish the scene, and also show us on which side of the room the cameras are located:

So we see that the scene is being filmed from the side that is to the therapist's left, and Lisa's right.

In filmmaking there's a convention called the 180-degree rule, aka the 180 rule. Like all rules, it can be broken but ideally you want to be breaking the rule intentionally, for a specific purpose* (e.g. to create a sense of unease or tension, to illustrate a character's shift in perspective or understanding, to signal a change in tone or atmosphere, to mirror shifting power dynamics, and so on). It's named for the 180° axis, which in this scenario is essentially an imaginary line, along which you have two or more characters situated, and which the cameras do not cross during the course of the given scene. Put simply, the rule governs where you can place your camera/s in the scene.

Here's a visual to help explain (courtesy of Adobe):

Note how we have two figures in this diagram, each with a camera placed behind them, and another camera facing them from side-on. The cameras in reality can shoot from anywhere within that half-circle that has been established for the scene (the dotted line is the 180° axis which the camera must not cross). So let's imagine the figure in blue is Lisa, the figure in red is the therapist, and the camera at the bottom of the graphic is showing us our wide shot we just highlighted above.

The camera behind Lisa gives us this over-the-shoulder perspective:

And the camera behind the therapist gives this over-the-shoulder perspective:

Rules exist for a reason, and this one acts as a guideline for viewers, maintaining a sense of continuity and creating spatial consistency so we as an audience understand where the characters are located specifically within the space they're occupying (here it's the therapist's office) and also in relation to one another. Ultimately, it makes the scene coherent for us, allowing us to focus on the 'action', in this case dialogue, facial expressions, and body language. If the camera kept crossing the 180° axis and was shooting from various different areas of the room, we would be disorientated, and become distracted by trying to figure out where we are being placed each time we cut to a new angle.

So crossing the invisible line can disorientate, but it can also be done to intentionally convey disorientation.

In this scene, Lisa has almost been lulled into thinking she's able to stick to 'safe' topics during the session: she asks the therapist about his plant and the discussion develops from there. She steers the focus to Carla briefly, and inadvertently to Betsy. Obviously she would prefer to not be having any kind of conversation with this man, and small talk about plants is no doubt far from her idea of enjoyable, but if she has to talk to him then these topics are just about acceptable to her, even if she is constantly grasping for control of the conversation. We can tell from her body language and fluctuations in her voice that she's uncomfortable, but she's playing along for now (although being a smartarse about it).

We get almost 2 minutes worth of conversation where we cut back and forth between coverage of Lisa and the therapist in a series of over-the-shoulder shots, mostly medium shots, with the occasional medium close-up on Lisa. Not only has she been lulled into a false sense of security (relatively speaking) but so have we. This repetition of shot type and content for almost two minutes doesn't have a soporific effect because we're engaged by the dialogue but it is disarming.

And then! The therapist says that magic word: Becky.

We can see instantly that Lisa is caught off-guard.

And then to really hammer home the unease, when we cut to the next shot, the camera has crossed the invisible line! Suddenly it's on Lisa's left for this over-the-shoulder close-up of the therapist:

It's jarring! What the hell are we doing over here?? We were so comfy and cosy watching this back-and-forth from the other side of the room, and now we've been flung to the opposite side without warning!

So when we cut next to Lisa, we feel her shock. She too is now shown in close-up from the other side of the 180° axis and she looks like she's just had the rug pulled out from under her feet.

And then we get a slow zoom in on Vicky Myers's extremely expressive face while the therapist talks, and we understand that Lisa has been left reeling by this mention of her late wife and the therapist's suggestion that they talk about her.

The scene ends there and we, like Lisa, are left a little stunned!

Imagine that somebody in the same room as you was watching this scene through earphones, so you could see the visuals but couldn't hear any sound. Even if you had never watched Coronation Street before, and had no context for what this scene was about, you would understand that this blonde woman had just heard something shocking in that moment and doesn't know how to respond.

If the cameras had stayed on the same side of the room for the entirety of the scene, and we had instead seen the slow zoom on Lisa's face from this side:

we would have sensed that she was stunned by the topic of Becky being brought up but would we have felt it as intensely? By breaking the 180 rule, the director has given us an additional visual clue to understand Lisa's emotional state in that moment. Vicky Myers is a strong performer and undoubtedly would have pulled it off regardless but this technique makes the effect extra potent. We have insight into what Lisa is feeling because to a lesser extent we feel it too!

*if you want an example of the 180 rule being broken for no discernable reason, look no further than the 16th December 2024 episode in which Carla and Lisa are enjoying a spa day and making Christmas plans. We start facing both women as Carla finishes giving Lisa a shoulder massage and then they have a little heart-to-heart conversation with Carla moving to the bed and Lisa turning to face her. This results in the camera being on Lisa's right/Carla's left:

Then, partway through the conversation, we suddenly cross the line and cut to the camera being on Lisa's left/Carla's right:

Then we cross the line again as Carla jokingly warns Lisa that she won't be cooking Christmas dinner:

Before we cross back once more. Not only do we keep crossing from one side of the room to the other but the colouring is also different as a result of the decor, making the change stand out even more. There's no way the rule break in this (emotionally and tonally) very soft scene was intentional as the content/atmosphere really doesn't warrant such a jarring change, nor indeed repeated 180 rule breaks. It seems more likely to me that it was somehow necesitated by circumstances on the day of filming.

WHAT THE FUCK IS THE 180° RULE ?

nothing to do with maths I swear

The 180° rule refers to an imaginary line which runs through two characters face to face, usually having a conversation. It is normally drawn 90° to the camera’s viewpoint in the establishing shot of the scene.

The rule is that the camera should remain on one side of the line.

-The Wolf of Wall Street (2013).

Jordan and Mark money song

-Taxi Driver (1976).

Travis talking to Iris

Following this rule insures the continuity of action and correct geography, ignoring it however creates instability.

-The Dark Knight (2008).

Batman interrogating the Joker

The Joker is trying to convince Batman that they are the same, breaking the rule makes their faces overlap, confirming what the Joker is saying.

-The Shining (1980).

Jack talking to Grady

Jack Torrance is talking to the ghost of Delbert Grady, in this case, breaking the rule is used to make the audience feel uneasy and show Jack’s mental instability.

Filmography;

-The Wolf of Wall Street (2013) Dir. Martin Scorcese.

-Taxi Driver (1976) Dir. Martin Scorcese.

-The Dark Knight (2008) Dir. Christopher Nolan.

-The Shining (1980) Dir. Stanley Kubrick.

what the fuck is composition ?

what the fuck are shot sizes ?

what the fuck are shapes within the frame ?

Editing - Basics

So you filmed your movie and now you’ve got to spend hours cutting it together just right. So dump your footage into your editing software and follow these tips to keep your editing clean and professional-looking.

Terminology: J - cut: a cut where the audience hears the audio before seeing the source. L - cut: a cut where the audience sees a picture before hearing its audio Both these cuts help “hide” edits by cutting sound and picture separately.

Match cut: a transition where two shots are matched by the action or subject and subject matter. 

Blend sound: use crossfades or similar effects and adjust sound gain to blend the room tone between two shots in the same scene together. This helps make the sound cuts seamless.

General rules: 180 degree rule: two characters in a scene should maintain the same left/right relationship to one another.

30 degree rule: the camera should move at least 30 degrees between shots of the same subject. If this rule is broken, it can be disorienting to the audience or look like a mistake. Rule of Six: Walter Murch identified 6 criteria for an ideal cut in order of priority. 1) Emotion - this is the most important reason to edit and is strongly related to story and rhythm. Edit to convey the feeling of your film. 2) Story - tell the story most effectively 3) Rhythm - pace the story. (Quick for action, slower for emotional scenes, etc.) 4) Eye trace - the location and movement of the audience’s focus within the frame 5) 2D plane of screen - obeying 180 degree rule and screen direction 6) 3D plane of action - the continuity of the space and where characters are in relation to each other

And Finally: Go with your instincts! If you feel a shot needs to be cut, cut it. Revisit your work. Sometimes you make poor decisions staring at a computer screen for hours on end. If you don’t like it the next day, tweak it.

A very useful rule beautifully explained.

Succession has all the hallmarks of HBO Prestige Television: big names, stunning production design, Shakespeare out the wazoo. It crosses the line as much in its shooting as its characters cross it morally, and just as often for kicks; see Episode 1.04 “Sad Sack Wasp Trap” (video for educational purposes):

I did a more detailed breakdown of a line cross (or breaking the 180 rule) in another post. Doctor Who is shot in a little more of a traditional style, whereas Succession goes the Friday Night Lights route of playing everything as a fly-on-the-wall narrative, with a floating camera giving it a bit of a documentary or reality show sans interviews. This feel also means casual blocking and line crosses are more common, but the way Roman and Kendall are juxtaposed here makes it feel quite intentional.

:00 Roman comes in Camera Right, and approaches Kendall Camera L. The next few cuts change from a wider to a slightly closer shot, with the off-camera actor somewhat dirtying the frame, while otherwise keeping their positioning the same.

:20 Kendall stands up and walks around his desk, but though he is briefly aligned with Roman, they maintain their respective R / L positioning, as does the next cut at :24.

:29 We cut from a single of Kendall Camera Left to a single of Roman Camera Left.

:31 Back to Kendall, who is Camera Left, and Roman still dominating R side of frame.

:33 Back to Roman Camera Left, similar to the shot at :29 but now with Kendall still in frame. This is the most jarring cut, because we go from a shot with both actors clearly in the frame, directly to a similarly framed shot where actors have ‘switched sides.’

:42 A single on Kendall, who now remains where he’d be repositioned, Camera R

:44 A single on Roman, who now remains where he’d be repositioned, Camera L

This is a short and sweet sample, but Succession does things like this constantly, not only in large crowd scenes where the moving camera and ensemble nature means crosses go mostly unnoticed.

For example, see Ep 2.07 “Return”. The scene where Shiv and Roman wheedle their mother at the dinner table moves the camera all over the place, with seven anchor points and a dozen shot sizes (more on this later) and no traditional ‘move right to left during a shot to reset the line.’ Does director Becky Martin do it because it feels otherwise a scene of three people sitting and chatting around a table – as opposed to twenty people at a n opulent party or three circling each other in a board room – would be less dynamic? Does she do it to represent how the verbal tug-of-war keeps shifting the power dynamic? Or is it to keep the audience off-balance with each character’s blunt attempt to knock each other off-keel? Maybe all of the above.

To demonstrate: fun with diagram! Shot numbers start at 1 as Caroline walks into the dining room with the pigeon, and ignores the two INT: KITCHEN shots of her getting more wine. Some of the cameras are clearly different takes/lenses for wides and closeups, but I labelled them the same due to essentially similar setups & angles; for example, the positioning in C CAM shot 3 of the table and shot 6 of Shiv’s closeup are similar angles with Shiv on the left, so same camera in the diagram for sake of simplicity.

It’s a 3:52 scene with 63 cuts (65 with Caroline’s kitchen forays).  Nearly every shot is on an angle, with a wide mix of CU and M shots, some clean some dirty, a couple even moving. It’s much more complex than the classic Gilmore Girls Friday night dinner setup, which is essentially four people around a table, camera in the middle, clean mostly-centered MS of each participant.

As the conversation escalates, more cameras get added to the mix, which also means we have fewer instances of going from Camera A to Camera B and right back to A. Because the camera is roving, we may be in a medium in 39, cut back to the same camera for 41 and we’re in a closeup. We are as constantly off-balance as Roman and Shiv.

Not always but often, the camera uses eye movement or head turns to initiate a cut to the character who is being looked at. (Shot 44, below; Shiv glances to Roman, narrows her eyes, then we cut to him.) Attempting to keep this flow with this many cameras can be a nightmare for editors, as changing one cut late in the edit is like knocking over a random domino in a line you spent three days constructing.

Just to up the degree of difficulty they throw in some rack focuses (:06 and :09 below).

My favourite cut may be shot 29 to shot 30 repositions Shiv from far right to left, demonstrating her considering Caroline’s offer while trying to play both sides:

  The key to breaking the rules is knowing them, and clearly Succession‘s directors know the rules. “Return” breaks them far more egregiously and over a longer time. But it’s the more egregious breaking I love more. Not only because it makes it clear it’s intentional (“Sad Sack Wasp Trap”‘s scene could have been a simple mistake lucked into, while “Return”‘s had to be painstakingly plotted) but because it feels better.

That’s a lot of me, my gut, and my aesthetic preferences. I can attempt quantification, of course: “Return” works better because we have the central dinner table to ‘ground’ us, while there is no similar feature in Kendall’s office; for the most part in “Return” the participants are seated and framed at about eye level, whereas Logan and Kendall are moving and the shots from similar positions constantly change heights as well as angles and sizes; “Return” is more conscientious about when it keeps characters on the same side of the frame for each camera, but then again they’re seated so it’s easier; etc etc.

But in the end, sometimes directing is more about gut feeling than rules and technique.

Stray Observations

– I’d be remiss not to note this has the freedom to work because the actors are firing on all cylinders: from Strong’s and Snook’s body language to Walter’s clipped calculating cadence to Culkin’s playing Roman as perfe bad at lying to his mother.

– It doesn’t hurt that “Return”‘s dinner scene also eschews the in-my-opinion-wildly-overused Succession favourite of using punch-ins to accentuate when a character has said or realised something devious or important.

– In regards to the punch-ins particularly and the shooting overall, the 1ACs are phenomenal at their jobs; just see the moment in “Tern Haven” where you see chef Rosa’s withering look right as the focus pulls to her from her overbearing employer, and realise they did it on purpose.

Shooting, Editing, and Crossing the Line on HBO's #Succession Succession has all the hallmarks of HBO Prestige Television: big names, stunning production design, Shakespeare out the wazoo.
