Change of Tune, Change of Mood

Music plays a subliminal but integral part of the film preview. But you may not realize just how big a role it plays in setting the stage for a movie until the trailer is stripped of its context and re-spliced with something dramatically different. These three classic movie previews use music to turn the premises on their heads and — wait for it — flip the script.

With the help of some clever editing and the right song, the music helps transform a horror movie to a comedy, and a family classic to a nightmarish scenario.

Not to be outdone, this video trades in a slapstick knee-slapper for a heart-pounding nail biter with the help of the suspenseful music from Inception.
