Yea, he definitely pulls off the sly look very well. But, if you've seen Wanted, there's a scene where he's let the hair grow for a day or two and you can see that he's had MPB. Hell if I knew....He still looks bad as sh*t sly.
The one funny thing about him to me is since I listen to his music, I know that he represents, in all sense of the term, true hip hop. Doesn't talk about shooting people or women or materialistic nonsense...Yet, I've only seen him be a bad, gangsta guy (or at least sinister) in the movies he's been in like Wanted and Smokin Aces. I guess it all comes down to this 'Hollywood making all us sly guys evil' thing....
