GGB as Roberto Duran is casting at it's finest!

Gael Garcia Bernal has been casted as Roberto "Mano de Piedra" Duran. Duran's one of the greatest fighters ever and, it'll be amazing to see GGB and company can bring us this generations Raging Bull. For those of you who don't know who Roberto Duran is: he's a world boxing champion in 5 weight division and has a career spanning over 5 decades. He's known as one of the key players in the lighter weight classes in the 1980's and compiled a record of 103-16(70 of those wins are by KO/TKO)... Oh yeah, he's also generally considered to be the greatest Latin American fighter ever. Casted somewhat ironically as Ray Arcel (Duran's trainer) is Robert De Niro. This is a big role to take on for anyone but, I think this casting is just perfect. Gael's weight is going to need to fluctuate similarly to the way De Niro's did in Raging bull so who better to "coach" him (I use that term loosely) on how to play the role than the man who played a very similar character and, did it better than anyone else? So, now that you've heard my thoughts on the matter what do you think about it?
