Hathaway said she was able to break the ice with co-stars Christian Bale and Tom Hardy by discussing Angry Birds.
"My first day I was sitting between Christian and Tom. I was like, 'Oh, these guys, it's a talent sandwich right here!'" she said.
"They're two of the best actors of their generation, could possibly be two of the best actors of all time. I was like, 'What are we going to talk about? Politics or world event? Or are we going to talk about the method?'
"We talked about Angry Birds. I'd never played it and they were talking about how they liked the game so I thought maybe I should try it.
"In spite of the fact that these are some of the most brilliant actors ever they're also very normal people. It was really lovely to hear about their lives and just get to know them."
