Matt Damon called on Robert De Niro for advice when he learned he'd have to pile on pounds for his role in THE INFORMANT - because the movie great had done such a great job of getting heavy for Raging Bull.
Damon gained 30 pounds (13.6 kilograms) to play Mark Whitacre in the new Steven Soderbergh film, and asked De Niro to help him through the process.
He tells WENN, "I just started eating... It felt fantastic putting on weight; I never had that much fun making a movie. I just ate whatever I wanted to.
"I talked to (Robert) De Niro before I did it and he had obviously piled on the pounds really famously for Raging Bull, putting on 60 pounds. I asked him about it and he said, 'Well, the first 15 pounds is really fun and then you have to go to work after that.'
"It was true except I found the 30 pounds to be really fun and then, kind of towards the end, I thought I should get rid of this weight, but I wasn't excited about getting rid of it."
