The Best and Worst Musicians-Turned-Actors

4. Frank Sinatra

The 30-time Grammy Award nominee Frank Sinatra also proved himself a worthy actor without having to give up his musical career. Sinatra starred in numerous successful films, including "Guys and Dolls," "The Manchurian Candidate," and "The Man With the Golden Arm." Sinatra won the Oscar for Best Supporting Actor in 1953 for "From Here to Eternity" and the Golden Globe for Best Actor in the 1957 musical "Pal Joey."
