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 'Avengers Assemble' as Black Widow got her into the best shape she's ever been in.
She said: "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."
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.
In an interview with UK TV show 'Daybreak', she revealed: "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."
Scarlett appears in the Marvel movie with an all-star cast that includes Robert Downey Jr. (Iron Man), Tom Hiddleston (Loki), Mark Ruffalo (Hulk), Jeremy Renner (Hawkeye), Chris Hemsworth and Chris Evans (Captain America).
