Boxing is the reason Mickey's face is all messed up. Crowe knows it's best to beat up on chumps.
http://en.wikipedia.org/wiki/Mickey_RourkeIn 1991, Rourke decided that he "…had to go back to boxing" because he felt that he "… was self-destructing … (and) had no respect for (himself as) an actor."[2] Rourke was undefeated in eight fights, with six wins (four by knockout) and two draws. He fought as far away as Spain, Japan and Germany.[19]
During his boxing career, Rourke suffered a number of injuries, including a broken nose, toe, ribs, a split tongue, and a compressed cheekbone.[20] He also suffered from short term memory loss.[21]
His trainer during most of his boxing career was Hells Angels member Chuck Zito,.[22] Freddie Roach also trained Rourke for seven fights.[23] Rourke's entrance song into the ring was often Guns N' Roses' "Sweet Child o' Mine."[24]
Boxing promoters said that Rourke was too old to succeed against top-level fighters. Indeed, Rourke himself admits that entering the ring was a sort of personal test: "(I) just wanted to give it a shot, test myself that way physically, while I still had time."[25] In 1995, Rourke retired from boxing and returned to acting.
Rourke's boxing career resulted in a notable physical change in the 1990s, as his face needed reconstructive surgery in order to mend his injuries. His face was later called, "appallingly disfigured."[26] In 2009, the actor told The Daily Mail that he had gone to "the wrong guy" for his surgery, and that his plastic surgeon had left his features "a mess."
