Film Trailer was played on the British edition of Whose Line.
A game for all four performers, one of which (usually Greg Proops) is a voiceover for a new film, with the title given by the audience. The other three act out the scenes the voiceover describes.
The most memorable playing featured Tony Slattery in one of his most embarrassing moments on Whose Line. He accidently ripped the front of his pants. When that happened, Greg was surprised on what he saw. Richard Vranch even took a look at it. The fiasco also caused a delay in the next game, Moving People, which never fully aired (as it happened in a compilation episode).
