Don't Ask Don't Tell

Don't Ask Don't Tell is a 2002 parody film directed by Doug Miles and written by famed gay screenwriter Tex Hauser. The 2002 winner of the Boston Underground Film Festival (BUFF) Bachus Award and the Neuchatel Sci-Fi Fest Audience Choice Award, the film was created by taking an old sci-fi movie—Killers from Space—overdubbing the soundtrack with humorous dialogue, and adding some new scenes, essentially turning it into an entirely different movie. The plot involves alien invaders with a machine that turns straight people gay.
