The Proclaimers song "I'm Gonna Be (500 Miles)" was prominently featured in the '90s dramedy Benny and Joon after actress Mary Stuart Masterson requested it be included in the film. The song refers to the challenging task of walking 1,000 miles (500 + 500) just in order to be with your love. Movies can be great showcases of grand gestures performed to express love between characters.
