Scarlett Johansson has "body worries." Despite her sex symbol status, the actress star has issues with her figure like all women do, but her all-action role in The Avengers as Black Widow got her into the best shape she's ever been in.

"Every woman has body worries, and I'm not exempt from that. But part of the by-product of spending that much time in the gym is that you can fit into a catsuit," she said.

Scarlett's spy character in the superhero movie is "very bendy and fierce," and the screen beauty had to work very closely with her stunt-double Heidi Moneymaker to get her fight scenes right:

"The idea is that she (Moneymaker) and I become one and we can start and finish each others moves and everything in between. And it's a lot of training and dedication and it hurts and it hurts and it hurts and then suddenly it doesn't hurt and you're getting it right and it's a great moment - you feel like you've accomplished something big."
