It might sound unlikely, Joaquin has recently announced his retirement from acting to concentrate on his rap career. The brooding Puerto Rican is better known for his acting roles such as Roman Emperor Commodus in Gladiator and a renegade in Buffalo Soldiers. His biggest success came, however, taking the role of Johnny Cash in Walk the Line, allowing him to showcase his musical talents as well as his acting skills. Sadly, or luckily, depending on how you look at it, the hip hop thing was all a big hoax and was made into the documentary film I'm Still Here.
