"[Jack nicholson] is a generous actor. He offers so much variety and the director decides to pick. He’s very practical too – like there’s a scene between he and I where he’s just had his heart attack and it’s kind of sensitive.

"He’s crying and he doesn’t know why he’s crying. He told me later: 'I was driving to the studio and I had to take a piss desperately, so I took a piss on the highway.'

"When I asked why he was so desperate, he said, 'Because you gotta drink a lot of water when you’ve got a crying scene. If you don’t have a lot of water in your body the tears won’t come.'"
