Interestingly, the funny in-joke teaser trailer for the film has nothing to do with its subject, doesn't feature any scenes or characters from the documentary nor does it ever mention what the movie is even about. It instead follows a trailer narrator called Jack (played by the legendary movie trailer narrator Hal Douglas who along with Don LaFontaine and Nick Tate narrated the trailers for almost every single big Hollywood blockbuster during the 1990's), who's in a recording booth trying to record the opening narration for the trailer for the Comedian, but since the film is not a typical Hollywood blockbuster, Jack is simply unable to find the right non-epic wording that would properly describe such a normal non-blockbuster movie.
Edited down from over 600 hours of footage.
