It was 10 p.m. Oct. 11, 1975.. 90 minutes left until the pilot episode of “Saturday Night Live” airs. Director Jason Reitman’s “Saturday Night,” released in theaters Oct. 11, 2024, dives into the never-before-told origin story of a show built to fail, yet destined to succeed. The film follows an ensemble of over 30 characters, which is an extensive range of people to cover in 109 minutes considering there are 10 minutes of credits and a bit of the live show. Yet it’s hard to imagine a movie about Saturday Night Live being made differently.
