Pregnancy Didn't Slow Scarlett Johansson Down

Pregnant Scarlett Johansson handled some of her own stunts while filming 'Avengers: Age of Ultron'

Stuntwomen didn't handle all the action for "Avengers: Age of Ultron" star Scarlett Johansson.

Johansson, who was pregnant for most of the filming, recently talked about some of her on-set antics at a press event at the Walt Disney Studious lot in Burbank, CA.

"I don't think you're allowed to ride a motorcycle when you're so pregnant, but I did," she said, per People. "I did all of the motorcycle riding. I embarrassingly rode some sort of mechanical-bull type of motorcycle, which goes nowhere and doesn't look cool, at all. But I had some very professional and amazing motor-cross morphing done that makes Black Widow look like a total badass."

Johansson gave birth to her first daughter, Rose Dorothy, with French fiancé Romain Dauriac in September 2014. The second installment of the Avengers franchise is due for release May 1 this year.

Despite taking on the motorcycle scenes, Johansson left most of the heavy lifting to others. Writer and director Joss Whedon told Entertainment Weekly that three different stunt doubles were used for the 30-year-old.

"We're not avoiding any of the danger, because the stuntwomen do the danger — as has always been the case," Whedon said. "She's very central to the movie, and when we heard [about the pregnancy], we scheduled things around that. She's not going to spend the whole movie carrying groceries. We didn't trim any scenes. We're like: We'll make it work."

Each of the doubles had dots on their faces that aided special effects artists' ability to digitally paste Johansson's likeness over theirs.

Chris Evans, who plays Captain America, noted the potential for confusion.

"It's always funny," he told Entertainment Weekly. "You walk by, 'Hey Scarlett — oh, weird. You're not Scarlett at all. Sorry.' A lot of fake Scarletts around."

Evans also confirmed that Johansson was pretty active during filming.

"She's just been great," he said. "It really hasn't slowed us down at all. She'll be running around, diving and jumping and doing these things and you're like, 'She seems like she's got this.'"
