When news of this movie first came out, the working title was originally Wolverines, the name of the first ever Saturday Night Live sketch that featured John Belushi and writer Michael O'Donahue. In the sketch, Belushi, a foreign man learning English from Michael, imitates everything he says, starting with "I would like to feed your fingertips to the wolverines" followed by other offbeat sentences involving wolverines. Then the teacher, after saying, "next," has a heart attack, falling on the floor, at which point Belushi does the same, imitating him like he'd been doing with the sentences. Then Chevy Chase walks out, looking like a crew member, with a head set on, and utters the famous line, "Live from New York, it's Saturday Night!"
The movie's title SNL 1975 technically doesn't fit since in 1975 the show was originally titled Saturday Night. Howard Cosell already hosted a prime time variety show called Saturday Night Live. Which is why Chevy Chase (and everyone else thereafter) says, "Live from New York, it's Saturday Night!"
On March 12, pictures were released showing Nicholas Braun playing Andy Kaufman, leaving Rockefeller Center. With record player in hand, no doubt after his Mighty Mouse performance. This raised confusion however, since Nicholas Braun was reported to be casted as Jim Henson, and not Andy Kaufman. On top of that, Ricky Wood (the world's biggest Andy Kaufman fan) really wanted to play Andy in this movie and pleaded with director Jason Reitman, who saw his pleas and did not answer.
Was confirmed by director Jason Reitman and cinematographer Eric Steelberg to be shot on 16mm film. This will make this film Reitman's first one shot on film stock since The Front Runner.
