'Avengers' Scarlett Johansson on 'Getting the Crap Kicked Out' of Her on Set (Video)

Scarlett Johansson was one of only a few actresses among a sea of men as she walked the red carpet at the premiere for The Avengers, Disney and Marvel's superhero ensemble pic, which will hit theaters on May 4. But like her character, Black Widow, Johansson was able to hold her own in the boys' club.

Dressed to kill in a black strapless outfit, the actress spoke to The Hollywood Reporter before heading into the El Capitan Theatre in Hollywood to watch the film on Wednesday night.

Anyone who's been paying attention has probably seen the clip from The Avengers featuring Johansson as Black Widow where she kicks some major bad guy butt with her hands literally tied behand her back. The actress talked to THR about the physical and mental challenges of the film's intense fight scenes.

"I think just kind of going back day after day, knowing that you’re going to get the crap kicked out of you and you do it willingly is sort of a challenge in itself, a mental challenge," she told THR. "But also I have to say that every time you fail at a stunt, it hurts until you get it right."

The film, directed by Joss Whedon, stars Robert Downey Jr. (Iron Man), Chris Hemsworth (Thor), Chris Evans (Captain America), Mark Ruffalo (The Hulk), Jeremy Renner (Hawkeye) and Johansson as a group of superheroes who must work together to save the world from Thor’s evil brother, Loki (Tom Hiddleston).

While many of the characters have already starred in their own films, Johansson's Black Widow has only appeared in Iron Man 2 before this upcoming tentpole. However, Johansson was quick to point out that the character has a long and interesting history in the comic book world.

"She’s really the first female superhero," she told THR. "There’s a huge rich background for me to kind of pick from and play with and layer."

Also known as Natasha Romanoff, Black Widow was created by Stan Lee (who attended the premiere on Wednesday),  scripter Don Rico and artist Don Heck, and has been appearing in comic books since 1964.

Johansson said her character in the film was "not different than she was in the comics."

"Joss [Whedon] and I were very conscious, very aware that she had this huge following. And why is that? Because she’s this very multi-dimensional, enigmatic character to play," Johansson told THR.
