Olivia Wilde spent all of her upcoming blockbuster movie 'Tron' wearing an ultra tight black bodysuit -- and so, she had to get the body to make it look good.
Wilde covers this month's Women's Health Magazine, and among other things, talks about how she got her body in seemingly perfect shape for the anticipated sci-fi sequel.
"I worked with a personal trainer, so I did about an hour of cardio five or six days a week," she began, though the workout didn't end there. "Weight training three times a week, mixed martial arts/fighting three times a week, and that's a lot more than my normal [routine]!"
DId it pay off? 'Tron' opens on Friday in IMAX and 3D, so viewers will have plenty of opportunity to judge.
The star also talked about her unconventional marriage -- she eloped with Italian filmmaker (and son of Prince Dada Ruspoli) Tao Ruspoli after only six months of courting. Even more unconventionally, they married on a school bus in Virginia.
So far, six years later, it's worked out.
"You're not thinking, 'We must be perfect!'" she professes. "It was, 'Hey, isn't this an optimistic thing to do? And if it lasts, we're lucky.'"
In fact, Ruspoli doesn't even mind when she's got love scenes with other actors -- as long as it's only on set.
"I think he likes it...It's a turn-on that I get to do these things. The confidence that comes along with doing well only makes you more desirable."
Wilde will also appear in another sci-fi flick, 2011's 'Cowboys & Aliens,' which co-stars Daniel Craig, Harrison Ford and Sam Rockwell.
