The Hidden World gets ten times funnier if you allow the characters to break fourth wall.
I hate that movie but hear me out. Characters must follow the script yes but the script is nonsense and they can't help themselves but make it known. In every. Single. Scene.
Every character is a real character (actor, if character reenacted their own story) except Light Fury, she's an animatronic.
That moment when she pushes Hiccup off of Toothless and everyone is laughing? They're laughing because this is the 30th take since Toothless always dodges her or dives down to catch Hiccup and Hiccup had been trying to ingrain in his head that I'll be okay, it's just a stunt Toothless, c'mon just this one time and we won't have to shoot this scene and get rid of it. But he doesn't listen. The Berkians are amused because they're already filled to the brim with the ridiculousness of the scene and Toothless' unwillingness to comply.
Toothless acting ooc, well the real Toothless is taking no bullshit and not following the script no matter how hard they try so they had to get a stunt double. The older takes which didn't make into the final copy are all actual Toothless and he's NOT following the story. Wearing the autotail makes him uncomfortable, he cannot muster up an excited expression. Ignoring Hiccup when he's in danger goes against his instincts.
Grimmel trying to pressurize Hiccup with night fury extinction? Multiple takes done because Hiccup keeps holding in snickers or interrupting him to invalidate his knowledge or sassing at him.
Snotlout being heard offscreen: "Who even wrote this thing? Terrible storytelling, I should've written it."
Ruffnut leading Grimmel on a goose chase cuz she knew she was being followed which actually validates Tuffnut's words of whoever captured her being the one suffering because they planned this.
Hiccup groaning in frustration and sighing before doing a scene.
Tuffnut offscreen when the pass over Hidden World: "The earth is round!"
The actual Toothless who got dismissed from acting cuz he refused to follow the script chilling off set and giving Hiccup looks when the later is trying to act a scene and Hiccup cannot focus like that because it's the same thing when you're giving a class presentation and your best friend keeps staring into your eyes and sending you inside jokes through your brains' Bluetooth connection.
The twins interrupt the shooting constantly to ask for clarifications because the script either goes against their experiences or they start rambling ideas, or correcting their own dialogues and actions.
Fishlegs providing a solution regarding death grippers within the first encounter because he read about them a lot.
Hiccup sneaking on the set to remove the death gripper's collars only to break them and realize that oops, these were props
Astrid sneaking in very politely and happily spoken sarcastic comments regarding the story in her scenes. It takes a moment to comprehend what she had said cuz her words don't match her acting mannerisms.
Snotlout with a red marker in his hand throughout the shooting crossing out and making corrections on his copy of the script, in full director/author mode.
Valka subconsciously rubbing off her makeup because itchy, stuffy, need off.
The only way to make the dragons take off for that last scene's shooting is bribing them with extra dinner they placed somewhere in that direction.
Basically, the story wasn't actually part of their life, they just gotta shoot that movie cuz contracts and cash grabs and what not.
Bloopers include bullying Grimmel nonstop and the gang being silly together.
