The I Give It a Year star plays a Wall Street trader in the film, which is about the global economic crisis of 2007-2008, but admits he is not good with numbers and was completely baffled by the movie's complicated financial jargon.

"I don't have a grasp of numbers," he tells the London Evening Standard. "I totally don't understand it. If I had to learn Japanese, I would parrot learn it and do it phonetically and it was exactly the same with numbers. I didn't understand a word of what I was ever saying in the film!"

The Big Short also stars Brad Pitt, Ryan Gosling, and Christian Bale, and is nominated for five Academy Awards, including the coveted Best Picture Oscar.

The awards will be handed out at a ceremony in Los Angeles on 28 February (16).

Brad Pitt, who is also a producer on the movie, previously declared he held greedy bankers responsible for the international credit crunch and he hopes the film will serve as a warning to future generations.

"It makes me want people to be better," he told the New York Daily News. "This entitlement that you can make money off the backs of others without being responsible for what it's doing to them or what it could do to them drives me crazy...

"The fact that no one was held accountable after this mass, mass failure drives me crazy so I want this story told. I'm really proud to be able to tell this story... It's something that you have to look out for because the experts will tell you nothing's changed. We've learned nothing, just new ways to do it."
