Princess Bride, The Easter Egg - Baseball Cap

During the opening scenes of the movie, a grandfather (Peter Falk) begins reading the Princess Bride story to his sick grandson (Fred Savage) in the boy's bedroom. You will catch a glimpse of the boy's baseball cap hanging near his bed. This cap was placed there by the movie's director, Rob Reiner, to fulfill a request by Mark Knopfler, who composed the music for the movie. Knopfler, former frontman for Dire Straits, agreed to write and perform the music for the movie, if Reiner would place somewhere in the movie a cap he had worn in the movie "Spinal Tap".
