Jason Reitman: How guest writing for SNL inspired Saturday Night

It’s Oct. 11, 1975, and the cast and crew of “Saturday Night Live” are scrambling to get the very first episode on the air. Director Jason Reitman (Juno, Up in the Air, Ghostbusters: Afterlife) chronicles those chaotic 90 minutes in his new movie, “Saturday Night.” He sits down with Tom to talk about how spending a week writing for “SNL” inspired the film, what it took to capture the excitement and tension of that night, and how truly revolutionary “SNL” was for its time.
