Sarah Lancaster stars in NBC's acclaimed action-comedy series Chuck as Ellie Bartowski Woodcomb, Chuck's ever-supportive sister who recently learned of his involvement in the CIA.

Lancaster has been turning heads as one of Hollywood's ascending young stars and has been included in Entertainment Weekly's Must List, a barometer of all that is "smart, sexy, and reeking of power."

She garnered attention for her recurring role as Madison Kellner on the family drama series "Everwood." Lancaster also starred in the one-hour dramedy "What About Brian," executive produced by J.J. Abrams, and appeared as the beautiful and ambitious blackjack dealer Veronica Harold on the drama series "Dr. Vegas," also starring Rob Lowe and Joe Pantoliano. In addition, Lancaster had a memorable arc as Lisa, an attractive gift shop girl and love interest for Zach Braff's character, on the hit comedy "Scrubs."

On the big screen, Lancaster played a love interest to Leonardo DiCaprio's character in "Catch Me If You Can." This past spring, she completed production on the independent film "The Good Doctor," alongside Orlando Bloom.

Lancaster was born in Overland Park, Kansas, where she grew up with her younger brother, Daniel. Her mother was a homemaker and her father was in real estate. It was her father's job that led the family to Mission Viejo, California, when Sarah was 10 years old. Soon after the move to Southern California, Lancaster began taking acting classes and landed a talent agent. Following a few months of commuting from Orange County to Los Angeles for auditions, she secured her first professional series regular role, starring as Rachel on "Saved by the Bell: The New Class."

Lancaster resides in Los Angeles. Her interests include travel, reading, the arts, and staying fit with such activities as tennis, hiking, ballet, and Pilates. She also lends her time to various charities and organizations including The Alzheimer's Foundation, the Orange County Performing Arts Center, Habitat for Humanity and Food on Foot.
