During Marvel's presentation at Comic-Con today, Kevin Feige confirmed that Ant-Man's Corey Stoll would indeed be playing a villainous role, while Evangeline Lilly has landed the female lead.  We'll keep the specifics of their characters until after the jump for those who'd like to stay spoiler-free, but they should come as pleasant if unsurprising news to comic fans.

Also starring Paul Rudd, Michael Douglas, and Michael Peña, Ant-Man opens July 17, 2015.  Hit the jump for more.

Straight from Marvel's presentation in Hall H at San Diego Comic-Con comes the news that Stoll will play the film's villain, Darren Cross.  Having had Dr. Hank Pym (Douglas) as his former mentor, Cross takes their company in a direction that Pym does not agree with.  Before long, Cross gets his hands on some Pym particles and becomes the villainous Yellowjacket.  Here's what Feige said about Stoll:

"Corey brings depth to every role he plays.  As a major part of the Ant-Man ensemble, we all wanted an actor who could be both cunning and sympathetic, and help create a character as dynamic as Marvel's best antagonists."

Equally interesting to Stoll's role is that of Lilly, who has been confirmed as Pym's daughter Hope Van Dyne.  Comic fans may recognize the similarity to the name Janet Van Dyne, the daughter of a prominent scientist who was a contemporary of Pym's and eventually took on the mantle of the Wasp.  Looks like the movie version is changing up the mythology a little bit, but that's par for the course.  And here's Feige's comment on Lilly:

“We’ve been fans of Evangeline for years, and couldn’t be more pleased that she’s agreed to join us on Ant-Man’s journey to the big screen. We look forward to audiences learning more about her character when she joins forces with Hank Pym and Scott Lang in 2015."

Filming on Ant-Man begins on August 18th.  Make sure to take a look at our Marvel panel recap on the film, and click here for all of our previous and continuing Comic-Con coverage.
