We talking about William Smith (the actor) or another Smith? The actor play in lot of low budget biker movies and was in a couple of TV series, way back in the day. He is a white guy. Hung around Venice, I have been told.
William Smith (the actor) was very strong and held the reverse curl record for quite a while. Also a top wrist wrestler. But that was probably around the late 60s & late 70's. He worked out at Vince's for awhile. Might try IMDB.com, if it was the actor your talking about. Should be a picture there, at that site.
