Forced to gain 30lbs for his latest role in The Informant Matt Damon has revealed that it was”probably the funnest time I’ve had working.”

Speaking at the Venice film festival Damon told reporters

“It was very, very easy to gain the weight,It was very, very fun, probably the funnest time I had working because I didn’t have to go to the gym after work and I just ate everything I could see.”

In addition to putting on a ton of weight Damon also got himself a new moustache, wig and glasses to play the role of Mark Whitacre a company vice president who turns FBI informant.

Looks like Damon had a whale of a time and enjoyed taking a part that forced him to look totally different to any role he has had before.

Sorry girls the once Bourne hunk now is a bit of a chunk.
