Pattinson will star in Bel Ami later this year, the first trailer for which was released this week.
Stewart, meanwhile, will update a classic fairy tale in Show White and the Huntsman, a possible trilogy that brought the cast together for a panel at Comic-Con this weekend.
How would the actress describe her version of this well-known character?
"She's got this amazing ability to channel fear, things that people are typically very afraid of, into this really focused, really charged, driving energy," Stewart said. "She's also like the people's leader and... truly doesn't let her heart cloud her mind. [She] doesn't let her mind get in the way of doing things she feels strongly about. Also, I get to have a sword and stuff."Charlize Theron meanwhile, plays the Evil Queen and made us laugh with her description:
"She's dark. She's a serial killer. I'm pretty much preparing to play a serial killer. I'm trying to ground it and make it something real. Watch out, Kristen."
Show White and the Huntsman comes out on June 1, 2012.
