Scarlett Johansson "brought her A-game" to the set of The Avengers.

The stunning actress plays the Black Widow in the comic book action adventure, which also stars Robert Downey Jr., Samuel L. Jackson and Chris Hemsworth.

Scarlett romped rough with the boys on set and participated in physically rigorous action sequences.

"I came in knowing that that was going to be a challenge and I brought my A-game," she said to People magazine. "Nobody took it easy on me."

"They were in full force, these boys, and I guess at times I had to remind them, like, I need my beauty sleep to keep up the visage.' They liked to play hard."

One scene in particular was incredibly hardcore for Scarlett.

"[H]e was going all-out against me," she shared. "I was like, Will you hold it back? I'm trying to work it out here. I've got smaller muscles than you.'

"I feel like they did try to kill me for five or six months. But it's OK. I held my own."

Scarlett enjoyed looking fierce in her costume while she was kicking butt. Unfortunately the garment didn't hold up at the end of the punishing shoot.

"I love it. I can't get enough of it," Scarlett gushed. "I think [the costume] was just shredded [at the end]. I don't think I even had enough to take home. There was like this much fabric left after all those fight sequences."

The Avengers will be released May 4.
