Hill insists he didn't have the slightest remorse for his co-star after he served up beatings on the set.
He explains, "The thing about Leo is, he's a really great actor, but he plays rough. We had fight scenes in the movie where we have to play physical with each other, and he basically beat the crap out of me for six months - and he's bigger then me, so I couldn't really retaliate and cause damage.
"I was like, 'I have to get this guy back. What do I do?'"
The opportunity came during a lunch scene in the film, during which Hill was supposed to eat a sushi roll.
He continues, "In one of the most emotional scenes in the movie, we're eating sushi and in the script he's supposed to say, 'Do you want that last piece?'... and I say, 'Yes,' and I eat it. (So) when we did the first take, he says, 'Do you want that last piece?' and I go, 'No, you have it.'
"So he had to do 100 takes of eating (sushi) over and over again and I was like, 'This is my revenge right here'. By the end of the night, he was on the floor, throwing up into a wastebin and everyone was like, 'Leo are you Ok?'
"The only two people hysterically laughing were myself and Martin Scorsese, because we have the same sick, twisted sense of humor. But I was like, 'That's what you get, man'."
