This interview was great:
SR: Had you met Willis before?
BM: I met him at this Andy Garcia movie I did, The Lost City. Willis is there and he'd had a couple drinks. We've all had a few drinks. And he says, "I just want you to know ..." I'm like, "Oh, fuck." He says, "I used to work as a page at NBC, and my job was to refill the M&M bowls and the peanut bowls in the actors' dressing room. And only you and Gilda ever treated me like a human being. You were nice to me." And I thought, Whew, that's good. I felt like, Shit, I did somethin' right, you know?
There's a reason he's so likable on screen, it's because he's so likable off screen. Some things you can't fake. Can't wait to see Moonrise Kingdom.
