Ironheart star Dominique Thorne, who plays the titular tech prodigy Riri Williams, has revealed that even she wasn't immune to Marvel secrecy: she didn't know villain Mephisto would be in the series until she was getting to film scenes with Sacha Baron Cohen.
"I didn’t know he would show up until we started filming, actually," Thorne told The Hollywood Reporter. "We were finally up to that portion of our filming, so definitely the wind down. And for the duration of the shoot, we had faux names. We talked a lot about Dormammu, and we kind of focused on him but it wasn’t until we were getting ready to shoot that scene with Sacha Baron Cohen that I even knew [that was him]."
