"It's a really strong, entertaining story. [Director] Adam McKay did an amazing job," Pitt gushed over The Big Short, which focuses on the buildup of the housing and credit bubble during the mid-2000s which led to America's recent financial crisis.

"You start talking about CDOs and adjustable mortgages and it's not the most entertaining material," Pitt said. "To get the message across, I don't think we could have ever done it without someone with Adam McKay's wit and his knowledge. He really is the smartest guy in the room."
