Return Of The Mack Mark Morrision
Matt says he and co-stars Brad Pitt and George Clooney enjoy playing practical jokes on each other.
However, Damon went on to reveal that he's never managed to successfully prank George Clooney and that Brad Pitt is the only one to get one over on him.
"I've never gotten George. The thing is, George is a pro. He's very tough to get. He's got all of them down, he's very, very funny.
The trio became good friends whilst they were filming the Ocean's trilogy and it was also the scene of George becoming a prank victim at the hands of Brad
"The best one I saw on George was on Ocean's Twelve when Brad had a fake memo translated and given to the Italian crew. It was this whole thing saying, 'Please do not look Mr. Clooney in the eye, only refer to him as Mr. Ocean or Danny.'"
He added in an interview with Shortlist magazine: "It was so the opposite of George that he was mortified when he found out, he was not happy about it. So that was the one time I saw someone get him."
Despite his A-List status Matt still tries to remain grounded and retain a sense of humour, sometimes during difficult situations.
"Even the movies that don't work you still work really hard on, so it's disappointing at first."
"But once you get past the disappointment of all that hard work not really going to a productive place, then you can mercilessly make fun of each other."
Practical Jokers: Matt, George and Brad share a joke while on the red carpet for Ocean's 12.
