Robert Mitchum is mentioned above ss a piano player, just once and briefly. I know that he wrote the theme song for one of his films, "Thunder Road." The movie is about hot-rodding moonshiners in the South, and the song has a sort of Southern Appalachian flavor, so I had always assumed that Mitchum had written it on guitar. Maybe not, unless he "doubled" on guitar and piano..

Another actor/songwriter mentioned above is Charley Chaplin, but no one made mention of his most famous song, the wonderful "Smile (Though Your Heart is Breaking)."

I was interested to read the stories about Groucho Marx as a guitar player, especially the one where he met Segovia. Is it necessary to mention the intrumental talents of his two brothers? Probably not ~ their playing is featured in almost every Marx Brothers film: Harpo's very lyrical and classical-sytle work on the harp, and Chico's humorous and eccentric approach to the piano.

A couple of folks made note of Audrey Hepburn playing guitar in one of her movies. Which one, please? I missed that one...
