Liev Schreiber and Daniel Craig got “really silly” on the set of new movie Defiance, reports.

Liev admits he was surprised by how down to earth Daniel was, adding the pair — who play Jewish brothers who take refuge in the forest to escape the Nazis during the Second World War — became the best of friends during filming.

He said: “I was really impressed that Daniel Craig was this major motion picture star who didn’t go to his trailer in between takes. I’m accustomed to that with A-list actors. They go to their trailer and then we all wait for them to come out. But Daniel didn’t. He sat with us and told stories and we had snowball fights and we bonded. Actually we got really silly. We spent a lot of time being silly.”

The 41-year-old actor also revealed the pair bonded over vodka, as consuming vast amounts of the potent alcoholic beverage was the only way they could stay warm while filming in Lithuania
