Next Gen 2011: Hollywood's Fastest-Rising Stars

Roos, 33, has been prepping for a career in entertainment since she was a child in Avon, Conn. At 9 or 10, she began hosting her own version of Good Morning America, moving from room to room with her family's video camera filming segments on the weather, current events and interviews with family and friends. "I modeled myself after Joan London," recalls Roos. But a college internship at GMA helped her come to the conclusion that she was interested more in the entertainment business than the news business. Upon graduating from the University of Arizona, Roos moved to Hollywood and accepted the first gig on offer: extra work on Ryan Murphy's short-lived WB drama Popular. From there, she landed briefly at Innovative Artists before moving into an assistant role in drama development at Warner Bros. TV in 2001. A decade or so later, the avid runner and frequent traveler -- recent trips include visits to Australia and Thailand -- is still there, hard at work on a range of series including CBS pair Person of Interest and The Mentalist and the CW's The Secret Circle.
