Jerry Seinfeld’s new movie, “Comedian” is due out this fall. It is a combination documentary/concert-film about his return to standup. The recently released trailer, however, has nothing to do with the content of the film. Rather, it pokes fun of the formula that most movie trailers follow: start with serious-sounding voiceover and build momentum with explosions and “funny” lines from the movie. It features Hal Douglas, the most recognizable in-a-world voice, playing himself and does a great job poking fun of the over-used stock phrases.
