Documentary
Still Dumb After All These Years (2006)
Through interviews with the Farrelly Brothers, the producers of the film and Jeff Daniels we learn about casting decisions, how the script was proved to be a very tough sell to certain studio parties, and about the relationship that developed between Daniels and Carrey on set and how the worked on some specific scene details together. Apparently the Farrelly Brothers sold the producers on the movie by acting out scenes in the office, and initially Steve Martin and Martin Short were wanted for the leads. While Carrey himself isn't interviewed here (which is a shame), there are plenty of clips of his antics from the film used to highlight certain moments in here.
