"So I'm sprinting around the back of the cab because I'm going to attack him. I come over and I hit him so hard that he goes right back in the cab. I start punching him in the face.
"Now this is all happening in front of a club. So the bouncers grab me and pull me off of him. The guy sees that I'm being held and he attacks me and tries to bite me on my nipple. He didn't hit me ... he sunk his teeth into my chest."
Luckily, the Oscar winner managed to keep the incident a secret from his friends and the public for over a year because he didn't want to get in trouble for the attack.
He said: "I go, 'Maybe he doesn't know who I am. I can't tell anybody about this. I can't tell my best friend about this.' So for a year I didn't tell anybody about it to see if anybody would know about it and it went away."
He added: "I have been in two fights this year, already. One that I started, one that I didn't. In both cases it was a big deal, it was all over the newspapers and I paid $30,000 each time.
"That's the price of doing business when you're famous and you punch somebody."
