The New Regime: Domnhall Gleeson

"I hate having my picture taken," says actor Domhnall (pronounced "tonal") Gleeson during our photo shoot. It's a surprising confession considering the infectious energy he brings to the set as he poses and pratfalls for the camera. One of a family of acting Gleesons-he's the son of character actor Brendan Gleeson, and his brother, Brian Gleeson, is also an actor-Domhnall seems to have his fingers in every aspect of the business.

His resume is already flush with choice roles in films like the final two Harry Potter installments (as the scarred, elder Weasley, Bill), 2010's Never Let Me Go and True Grit, and the recent adaptation of Anna Karenina, but that's just the beginning. He earned a Tony nomination in 2006 for his part in the Broadway play The Lieutenant of Inishmore, co-wrote and starred in sketches for the six-part Irish comedy show, Your Bad Self, and wrote and directed two short films- 2009's What Will Survive of Us, which he refers to as "the anal sex one," and Noreen, which stars his father and brother as incompetent police officers.

Writing, acting, directing - is there anything the 29-year-old Dubliner can't do? "I haven't done any interpretative dance yet," he says with a long sigh. But he has gotten a haircut. When asked about what happened to his trademark long ginger locks, he laughs and says, "Really...l'd done as much with my hair as I possibly could."

Coming up, he'll play the romantic lead opposite Rachel McAdams in About Time, and he's learning to play guitar for the rock comedy Frank, for which he'll go head-to-head with Michael Fassbender. And it turns out he's camera-shy when filming as well, admitting that being in front of the camera is nerve- wracking. "What's so terrifying-and exciting - is that it remains forever."
