Vin Diesel is a actor----the rock is a wrestler----these two don't even come close----
what you have to remember is Vin Diesel has earned everything he has done.........not to take anything from the rock but his role could have been played by any of the top 5 wrestlers and the movie would have done the same in terms of money-----
The rock will fade away while Diesel will be earning 20 million plus a movie and calling his own shots-----The rock brings nothing more to the table then stallon, Arnold and van dam did in terms of acting---although the rock does bring a fan base that has some gout to it---it can't be long lasting-------
Vin Diesel will hit you in a different direction other then just some dumb big guy----plus word is Diesel is a tink(which believe it or not is a plus in his industry--as long as it is only known by the people in it) Their are now a ton of directors, producers---casting agents that are tinks----and these guys stay together...... peace
