“SNL”'s Best Sketch of All Time? The “Saturday Night” Movie Cast Picks Their Favorites (Exclusive)

Gabriel LaBelle, Cory Michael Smith, Lamore Morris, Ella Hunt and more also star in the 'Saturday Night Live'-focused film, directed by Jason Reitman

Live from New York, it's the movie cast of Saturday Night!

Actors from the upcoming Jason Reitman-directed film (in theaters Oct. 11), which will recount the behind-the-scenes happenings of the very first episode of Saturday Night Live, have plenty of choices when it comes to a best sketch from the long-running variety show. Ahead of their movie's Tuesday, Sept. 10 premiere at the Toronto International Film Festival, several cast members shared their favorites exclusively with PEOPLE.

"I'm obviously going to change my mind tomorrow," quips Rachel Sennott, who plays former SNL writer Rosie Shuster in the movie. "But I'm just going to say one of my favorites, which is the Andy [Samberg] Lonely Island one, where it's like, 'I threw it on the ground.'"

"I really love Adam Driver comes in for career day and he's this really old man, this oil man, and Pete Davidson is his son, and it's just hysterical," says Gabriel LaBelle, the actor who embodies SNL creator Lorne Michaels.

"His undercover boss is really good too," chimes in Dylan O'Brien, who plays Dan Aykroyd. "One that comes to mind is, I always love the Ryan Gosling 'Santa Baby' one. They basically get kinky for Santa."

"[Writer] Julio Torres' 'Wells for Sensitive Boys' kills me," says Ella Hunt (playing Gilda Radner), while Cory Michael Smith (Chevy Chase) prefers the Spartan cheerleader sketches. "Cheri Oteri, Will Ferrell. It's brilliant."

Lamorne Morris, who plays Garrett Morris (no relation), "would say Eddie Murphy's 'Too hot in a hot tub.' So good. That's got to be up there. Eddie Murphy's my idol."

As for Reitman's "favorite sketch of all time," the filmmaker doesn't hesitate: "Steve Martin doing his 'very special Christmas wish.'"

In August, Vanity Fair shared a set of first-look photos from Saturday Night. Among those featured in the images are Kim Matula as Jane Curtin, Emily Fairn as Laraine Newman and Nicholas Braun as Jim Henson. Others include Matt Wood as John Belushi, Jon Batiste as Billy Preston, Matthew Rhys as George Carlin, Kaia Gerber as Jacqueline Carlin, Cooper Hoffman as Dick Ebersol and J. K. Simmons as Milton Berle.

According to Vanity Fair, "The story starts at 30 Rockefeller Center at 10 p.m. on October 11, 1975, and culminates with the first-ever broadcast of Saturday Night Live... The movie plays out in real time over about 90 minutes, and while there are certainly comic moments, the film isn’t intended to be a laugh riot. What unfolds is less a comedy than a ticking-clock suspense movie."

Reitman, 46, told Vanity Fair in an accompanying interview that Saturday Night "is about not only the first seven actors, but the writers, the art department, and everybody who came together at the last second to change television."

"The format was unlike anything anyone had ever seen before," he added of the film, which was written by Reitman and Gil Kenan and also stars Tommy Dewey as Michael O'Donoghue, Nicholas Podany as Billy Crystal, Andrew Barth Feldman as Neil Levy and Finn Wolfhard as an NBC page.

Some of the cast members have spoken out previously about advice they have received for the upcoming film, and vice versa. Back in March, Garrett Morris told PEOPLE that he had spoken with Lamorne Morris about playing him.

"He has to be a guy who's dealing with some young people," said Garrett, 87, who was being recognized at the American Black Film Festival Honors in Los Angeles. "When I was inside in that life, I was 39 years old and the rest [of the cast], they had just come out of high school and college."

"The Black thing is you take longer to do what the younger White people do, and you usually have to do it two or three times as good," he continued, adding of his conversation with the "wonderful" Lamorne, 40, "We talked about that and he already told me he's going to play it like that — an older Black guy who's dealing with these younger guys. I said, 'Wow, man.' "

Saturday Night is in theaters Oct. 11.
