Rupert wrote the movie’s original songs and musical underscore, sang the movie’s title song, acted in a scene with Demi Moore, and arranged two pop standards vocalized on screen by Demi (whose singing voice was supplied by Chrissy Faith, who can also be heard on many of Rupert’s albums and productions).
No Small Affair is a 1984 American comedy-drama film directed by Jerry Schatzberg and starring Jon Cryer and Demi Moore. Cryer, Jennifer Tilly and Tim Robbins make their film debuts.
The 16-year-old amateur photographer Charles (Jon Cryer) accidentally takes a photo of Laura (Demi Moore), and falls in love with her when he develops the picture. He finds out that she works as a singer in a bar, but is about to be thrown out. Although rejected at first by the 22-year-old, he attempts to boost her performing career by starting an ad campaign behind her back — with unexpected results.
