Dylan O'Brien Jokes He's 'Okay' If Dan Aykroyd 'Hates' His Saturday Night Portrayal of SNL Comedian (Exclusive)

Dylan O'Brien has big shoes to fill in Saturday Night — and he's fine with that!

Speaking with PEOPLE about the upcoming film, in which he stars as Dan Aykroyd, the 33-year-old addressed the pressure that comes along with playing someone still living.

And for O'Brien, "I'm okay if my guy hates it," he jokingly says. "It's acceptance. That was my method."

While he hasn't yet met Aykroyd, 72, O'Brien is looking forward to when he gets to do so, saying he "can't wait" and is "0% terrified."

"I hear we're very similar, in a way that I never knew," the Teen Wolf alum says. "I feel like we're going to get along."

Aykroyd appeared on SNL from 1975 to 1979, starring in sketches like The Blues Brothers and Coneheads, both of which led to spinoff feature films. He also worked as a writer for the late-night comedy show, and bagged five Emmy nominations.

Speaking to Entertainment Tonight at the New York City premiere of Ghostbusters: Frozen Empire in March, Aykroyd opened up about O'Brien’s upcoming portrayal of him in Saturday Night.

“We’ll see. You know what, I’m just glad the young actor got work,” the comedian and actor joked. “If he’s compelled to play me, well, I’m glad he got work.”

Saturday Night is in select theaters Sept. 27 and everywhere Oct. 11.
