Robert De Niro fell asleep on Hilary Swank while they filmed 'New Year's Eve'.

The veteran actor plays the part of a man who is dying in the comedy movie, and while Hillary - who portrays his daughter - was expecting him to go "method", she was not prepared for him to get so deep into his role that he took a nap.

She said: "You hear all this stuff about Robert De Niro, and he's method. This is a comedy, but he's dying. I didn't want to get in anybody's way. So he was laying there and he saw me, and then he shut his eyes, and I was thinking, 'Wow, he's giving it to me. We're connected here. We are connected. Me and De Niro are method.'

"I started getting a little emotional. The camera was not on me, but we were just getting into the mood, of the father-daughter relationship, and the father dying. I was feeling it, and I was going deep with De Niro. The next thing I know, he's like, 'Anyone got that coffee?' I was like, 'Oh my god, he was sleeping!'

"I thought he was going deep for me. The truth is, he'd been in that bed all day and he took a nap."

However, the Oscar-winning actress admits she was delighted to work with the star.

She said: "Robert De Niro, for me, he was on my bucket list. He was on the top of the people I have to work with before it's all said and done, so I got to check that off."
