The screenwriters of the film, Scott Alexander and Larry Kraszeski, are a pair of good friends, and they work together very well, even their voices are very similar.
At the beginning, many actors were audited for the film, but the director and producer were greatly moved by the preparations of Kim Carey, so Kim Carey was cast as the leading actor.
During the filming, Kim Carey not only asked everyone to call him Andy, but he also imitated Andy Kaffman in his own behavior, always making troubles, and often clashing with the actors who played the opponents in the play.
