Cory Michael Smith is playing Chevy Chase in the upcoming movie ‘SNL 1975’

DEADLINE: Lamorne Morris, Dylan O’Brien, Cory Michael Smith and Matt Wood have joined the cast of Sony Pictures’ SNL 1975, which will be directed by Jason Reitman and based on the real-life behind-the-scenes accounts of the opening episode of Saturday Night Live.

Morris will play Garrett Morris, O’Brien will play Dan Aykroyd, Smith will play Chevy Chase, and Wood will play John Belushi. The original screenplay is written by Reitman and Gil Kenan.

On October 11, 1975, a ferocious troupe of young comedians and writers changed television forever. SNL 1975 is the true story of what happened behind the scenes that night in the moments leading up to the first broadcast of NBC’s SNL. It depicts the chaos and magic of a revolution that almost wasn’t, counting down the minutes in real time to the infamous words, “Live from New York, it’s Saturday Night!”

The screenplay is based on an extensive series of interviews conducted by Reitman and Kenan with all the living cast members, writers and crew. Reitman, Kenan, Jason Blumenfeld, Erica Mills and Peter Rice are producing.

Best known for his role on as the Riddler on the Fox series Gotham, Smith can currently be seen as Julianne Moore’s son in Todd Haynes’ May December. He most recently starred as Varian Fry in Anna Winger’s limited series Transatlantic opposite Gillian Jacobs and Corey Stoll for Netflix. Smith has also worked with Haynes in both Carol (as private investigator Tommy Tucker) and Wonderstruck.
