When Avengers: Age of Ultron hits theaters, Scarlett Johansson ‘s baby bump won’t be visible. The actress got pregnant just before filming began, which slightly complicated the production process. Director Joss Whedon says in Entertainment Weekly’s double issue. “We didn’t trim any scenes. We’re like, ‘We’ll make it work.'” To accommodate 29-year-old Johansson’s pregnancy, Whedon hired three stunt doubles for action scenes. That’s when the movie magic begins. The stand-ins wear dotted maps on their faces, which will serve as guides for visual-effects artists who will graft Johansson’s face onto their bodies in post-production. Chris Evans, who recently worked Johansson on Captain America: The Winter Soldier, said, It’s always funny.You walk by, ‘Hey, Scarlett—oh, weird. You’re not Scarlett at all. Sorry.’ A lot of fake Scarletts around.”
