(CBR) Marvel Studios and Joss Whedon have a tough act to follow, at least as far as "Avengers" villains go. Tom Hiddleston’s Loki is beloved by fans worldwide, so much so that a diehard contingent petitioned for Loki to have a solo film.

But studio President Kevin Feige isn’t worried about response to James Spader’s titular evil android in "The Avengers: Age of Ultron." To hear him tell it, Spader’s villain is well on his way to becoming a classic.

“Our bad guy is great. I think people are going to very, very excited to see what we’re doing with the voice that Joss [Whedon] is bringing to life with James Spader for Ultron,” Feige told Movies.com during recent press rounds for "Captain America: The Winter Soldier." “We love Ultron from the comics, and have always loved Ultron, and at no point do we want him to just be a robot. We want him to have an extreme personality and attitude, and James Spader is doing an unbelievable job.”

Beyond Ultron, Feige admitted that Marvel is very much considering making a movie starring a female superhero. However, he doesn’t expect the studio’s first female-driven film to focus on Scarlett Johansson’s Black Widow.

“Frankly, if we do a Black Widow movie after "Age of Ultron," when she’s been central in three or four movies I don’t think we’d get the quote unquote credit for it,” he told Badass Digest. “People would say ‘She’s already a big giant superhero!’ But if we had a great idea, we’d do it.”

Instead, Feige and Marvel have batted another name around: Carol Danvers, known to readers as Captain Marvel.

“We’ve talked a lot about [Captain Marvel],” he said. “I think that would be very cool.”

"The Avengers: Age of Ultron" bows on May 1, 2015.
