The 32-year-old actor - who is married to Hollywood star Demi Moore - admits he wants to work on a cowboy-themed movie, but doesn't think it will happen because people are no longer interested in the genre.

He said: "I really want to do a western at some point that's like a real super gritty, gritty western. But I don't know if I'll get to do that because people don't really go to westerns anymore. But at some point, I'd love to."

The hunk also admits his 'Killers' co-star Katherine Heigl is determined to do a good job when working, but still remains a "great person".

He told MTV Australia: "Katherine's the kind of person who considers running to be a stunt, but at the same time what it is that she brings is so valuable, and she's actually a really great person on top of it.

"She just knows what she likes to do and knows what she doesn't like to do and brings it."
