The Marvel Cinematic Universe has yet to add time travel to its bag of tricks, but to get the right villain for Agent Carter's second season the showrunners had to pull a bit of magic. In an interview with /Film, executive producers Tara Butters and Chris Bingess revealed that the new season's big bad will be long-time Iron Man villain Madame Masque. When asked about villains from the 1940s period which Agent Carter exists, Butters explained that there were few available to choose from.
"Here’s the thing. It’s a little hard. In the comic books, a lot of the Marvel period, there are issue rights," Butters revealed. "Our villain from the season is very much a Marvel villain that we co-opted a little bit like we did Dr. Fennhoff in the first season."
Bingess describes their Madame Masque as "a '40s version of that villain," where both her visual design and backstory were changed to fit the period.
"I think we’ve changed the look of her a bit obviously," said Butters. "We’ve made her an actress, which is very Hedy Lamar. She was a ‘40s siren actress who was also a scientific genius, so that’s part of what we’re mining with this character."
Butters goes on to say that an actress has already been chosen to play the role, but they're holding back on announcing it at this time. The producer/showrunners says however that the character's gender was one of the key reasons they chose her.
"For me it is, because I feel like that is something that… as much as there are not enough female heroes just on television, I feel like having a female villain is just as equally powerful," said Butters.
"I also think because she's a female villain, her story informs Peggy's story in a unique way and vice versa," Dingess adds.
