I think he looks fantastic. I think we were just used to seeing him all bulked up to play Ali. He hasn't done too much in between. We saw the trailer for I Robot last weekend, it looks pretty good. He has come a long way since Dj Jazzy Jeff and the Fresh Prince.
I saw him on Leno the other night and noticed he looked different too. ( still looks good mind you) I thought he looked like his hairline was receding and that is what was different.
