Kevin Spacey as Mickey Rosa in a scene from '21'

The actor plays a ruthless academic intent on swindling millions from Sin City's famous casinos in the new movie, but insists he didn't live the high life while working in the gambling mecca.

He says, "I've been to Vegas a lot of times over the years, and in a sense I'm over it.

"We were there about a month. I didn't party and I didn't gamble. You just can't when you're on a movie.

"I played tennis on the days when I wasn't working."
