Will Smith is reluctant to play a villain on the big screen - because it would conflict with his natural instinct to make people laugh. The Oscar-nominated actor - who shot to prominence in hit TV sitcom The Fresh Prince Of Bel-Air - has stepped away from comedy to star in such movies as Ali, The Pursuit Of Happyness and I Am Legend, but he insists funny films remain his top choice of work. And he'd only ever contemplate playing the bad guy if the role carried an important message. He tells British magazine Empire, "I enjoy inspiring good feelings, that is fun for me. Comedy I would say is my most fun. How people react to Hitch and The Fresh Prince Of Bel-Air, there is nothing that matches that. "I'm sure there is a bad guy at some point that has the right message. Scarface had the right message about power and drugs and it showed you exactly where that mess was going to end up."
