Well you know what, I got to thinking about those actors & actresses that saw commercial success as musicians, and there are many, but here are five great actors and actresses that also saw success as musicians!
At number 5: David Hasselhoff (Starcrash).

Today we all know Mr. Hasselhoff for his drunken antics that made it to Youtube... It is sad because the man is a great actor having torn up the small screen in the 90s with such shows as, 'Baywatch', but his career (at least on the international stage) has been a major sensation since the at least the 1970s!
For more information on David Hasselhoff please enjoy this trailer for one of his better movies, Starcrash (1979).

Will Smith is another one of those Hollywood staples that frequently has a movie that is in some level of production, but one of the things that he is lesser known for is the fact that Mr. Smith has also periodically had a pretty successful music career, including having done some of the music for one of his biggest hits, Men In Black (1997)!
