In Rome, I loved seeing the Caravaggios. There are churches in Rome that have Caravaggios, and there's one, not far from Piazza Navona, that has the best, I think: St. Matthew with the money.

I remember hearing a good story about Jack Nicholson working with Stanley Kubrick on The Shining [1980]. Nicholson was saying that, as an actor, you always want to try to make things real. And believable. When he was working with Kubrick, he finished a take and said, "I feel like that was real." And Kubrick said, "Yes, it's real, but it's not interesting".

I remember working with Jackie Chan on Shanghai Noon [2000], and when we were working on the script, I thought that my character thought about being an outlaw the way a kid today would think about being a rock star, as a way to impress girls. So it was just kind of a funny idea, but once we had that idea, it changed the character and made it something that was funnier to me to play.

I guess that's the thing about Rome: It never changes.

Anna Wintour has a reputation - she can be very intimidating - but that day [Valentino show] she was just smiling and laughing. That was my first time meeting her, and she seemed like she was having a great time. Everybody was enjoying themselves.

If a movie goes south, it might not capsize me the way it used to. But I still have a terrible fear of failure. I'm a huge worrier.

Australian cattle dogs, are not like Labradors, where they just like to just sit around by the fire and get petted. They're working dogs, so they have a lot of energy, and they can drive you crazy.
