Hollywood films are full of cameos by famous musicians, and this happens for all sorts of reasons. Often, filmmakers like to give their famous friends a small role in their films for fun, like Stephen Spielberg did with Phil Collins in Hook. Sometimes, filmmakers cast a renowned musician in an ironic way, as David Lynch did for Mulholland Drive with Billy Ray Cyrus. Occasionally, musicians even prove capable of carrying a role that's a bit more substantial than a cameo, like Randy Travis in The Rainmaker.
