accidentally paused at the perfect moment (Frannie is trying to shoot her shot with Fraser, Ray is rolling his eyes so hard they might just fall right out of his head, and Fraser just looks like shocked pikachu)
Inspired by my realization that RCMP Officer 2 (Pilot) and Jocelyn Kerr (The Ladies' Man) are both played by Jennifer (Jen) Parsons, I decided to check the cast list from IMDb and see if there were any other actors who appear as 2 (or more) different characters in the due South universe. To my surprise, there are several from the pilot alone! Many of these characters lack readily available screenshots (and some I couldn't identify by name alone) so I went through the episodes to compile this side-by-side list.
I may continue this search through the rest of the episodes, mainly relying on cast information from IMDb, the credits of the episodes themselves, and these wonderful annotated transcripts. And since some characters are unnamed and/or uncredited, maybe I'll even spot some new ones! Also, I am 100% open to contributions and/or corrections, so if anyone has anything they'd like to add, I'm all ears!
Without further ado, listed by actor and mostly in order of appearance...
Paul Gross - I almost skipped PG before remembering that he has indeed played another character on dS! So here's PG as Benton Fraser (Pilot) and as Frannie's German fiancé (Dead Men Don't Throw Rice, S4E5)
2. Kimberly Ange - RCMP Officer 1 and also appears in Victoria's Secret Part 2 (S1E21) as an attorney named Boswell (credited as Kim Ange)
and
3. Jennifer Parsons, the one who started it all - RCMP Officer 2 and also appears in The Ladies' Man (S4E3) as Jocelyn Kerr, who wants to have bark tea with Fraser (credited as Jen Parsons)
4. Scot Dentor/Denton - RCMP Officer 4 (credited as Scot Dentor in the pilot but listed on IMDb as Scot Denton). IMDb also identifies Scot Denton as the uncredited actor who plays Pierce (the ambassador targeted in The Edge, S2E9)
5. Barry Kennedy *** - This one I'm not so sure on. Barry Kennedy plays a character called Bert Jenkins in the Pilot but as far as I could tell, no character is called this aloud in the episode itself. Working backwards from Kennedy's other dS credit (Sgt Eddie Polito in The Ladies' Man, S4E3, uncredited, per IMDb), I still struggled with a definitive ID. Based on the annotated transcript of TLM, I believe the man on the right in TLM screenshot below is Kennedy's character Polito. Based on this, and the fact that the supporting characters seem to be credited roughly in order of appearance in the Pilot, my best guess is that Kennedy's dS Pilot character is the pilot who talks to Fraser about the lack of geese and beavers. They look like they could possibly be the same guy?? Maybe?
6. Philip Williams - Herb Lantrell, the pilot who gives Fraser the list of American dentists who'd been hunting in the Pilot, also appears as the arms dealer Lloyd P Nash (the P does not stand for pertinent) in Bird in the Hand (S2E4).
7. JD/Jack Nicholsen - the unnamed Airport Hustler (credited as such even though he does return the money to Fraser at the end of the Pilot) is also 2 other characters: Caulfield (one of the bad guys stealing pets in The Wild Bunch, S1E15) and Joey (Denny Scarpa/Lady Shoes' trigger man in Odds, S4E6)
8. Gene Mack - the Chicago Desk Sergeant in the Pilot is also credited as Mason Dixon, the associate of Devlin (the boxing trainer in Mountie & Soul S3E7). Mack is credited as Chicago Desk Sergeant but does have a name tag in the Pilot, although it is quite blurry.
9. Dan Lett - Dr. Weingarten (the dentist in the Pilot) is also Carver Dunn (the creepy fan who uses blackmail to barter for the singer Tracy's stockings in Mountie Sings the Blues, S4E7)
10. Ramona Milano - Francesca Vecchio! And also appears as Deputy Bernie in Dr. Longball (S4E1).
Dr. Longball of course has other main cast members playing different characters, but I plan to cover those as I make my way through the episodes chronologically in the hopes that it'll help me keep track of which actors/episodes I've checked.
11. Sandi Stahlbrand - TV Reporter Shelley Perry from Channel 6 News in the Pilot and TV Reporter Tracy Wightman (apparently from Channel 7) in Red, White, or Blue (S2E17)
12. Kevin Rushton - an honorable mention! I didn't think to include Rushton until I saw the IMDb trivia point him out in the bar scene in the Pilot. Rushton does stunts on the show and presumably appears in several episodes, which I think thereby technically meets the brief of playing multiple characters (unless there is a case to be made that Rushton plays a recurring character role? which could be an interesting take). But either way, shout out to all the dS stunt folks!
IMDb specifically credits Rushton for appearances in Diefenbaker's Day Off (S1E2), A Cop, a Mountie and a Baby (S1E9), You Must Remember This (S1E11), and One Good Man(S2E8).
