Tonys 2012: Jessica Chastain Reveals Red Carpet Secrets, Admits She Is 'Freaking Out' About Broadway Debut (EXCLUSIVE)
So, just what is her secret to looking so good?
"My trick is to have amazing people around me," she told Celebuzz at Broadway's biggest night. "I have such a crazy schedule, so [stylist] Elizabeth Stewart helps me so much with finding things that she knows I'll love."
"I also have wonderful hair and makeup [people]," she added.
Soon, Chastain, who in January received an Oscar nomination for her performance in The Help, will be making her Broadway debut in The Heiress, a play based on the short story by Henry James.
"I'm so nervous and very excited," she said, on preparing for the role. "I'm so happy to be in a rehearsal room with Moises Kaufman, David Strathairn and Dan Stevens. It's exciting."
Dan Stevens, of course, plays Matthew on the PBS miniseries Downton Abbey; and even though Chastain admitted she's a fan of the Emmy-winning series, she's still trying to play it cool in front of her handsome costar.
"I've seen some Downton Abbey," she said. "But I don't want to go up [to Stevens] and be, like, 'Hi!'"
Chastain, who in 2011 appeared in six -- yes, six -- films, has another busy year ahead of her. Among the films she'll appear in: Kathryn Bigelow's untitled follow-up to her Oscar-winning The Hurt Locker, about the killing of terrorist leader Osama bin Laden.
