Hollywood best friends Will Smith and Tom Cruise coach each other for movie roles in a bid to sculpt and polish their performances. Smith reveals Cruise spent 15 hours making notes on new movie I Am Legend, so he could give his pal advice.

The Valkyrie star then jetted across America on Tuesday to appear alongside his friend at the movie's New York premiere.

Smith tells the New York Daily News, "It seems like we'd be in competition with each other, but we're not. We help each other."
