Ellen Pompeo as
Meredith Grey An earthy blonde with soulful eyes and a mischievously playful smile, burgeoning actress Ellen Pompeo 's career began to soar after a memorable turn as Jake Gyllenhaal 's sympathetic love interest in director Brad Silberling 's introspective family drama Moonlight Mile . With roles in such eagerly anticipated films as Steven Spielberg 's Catch Me If You Can (2002) and the comic-book adaptation Daredevil (2003) following close on the heels of what many considered an Oscar-worthy performance in Moonlight Mile , it seemed as if Pompeo was on the verge of becoming a well-known star. A native of Everett, MA, Pompeo got her start as an actress with a pair of appearances in the popular television drama Law & Order . Subsequently cast in the coming-of-age teen-sex comedy Coming Soon (1999), Pompeo continued to refine her skills as a harried waitress in the comedy In the Weeds (2000) while also appearing in a pair of comedic shorts entitled 8 1/2 x 11 (1999) and Eventual Wife (2000). Her recognition factor on the rise, numerous fans and critics considered Pompeo 's turn in Moonlight Mile to be her breakout role.

Patrick Dempsey as
Dr. Derek Shepherd Noted for playing quirky and charmingly shy young men, contemporary American actor Patrick Dempsey became a rising star in Hollywood during the late '80s and '90s. A state downhill skiing champion in high school, he began performing nonprofessionally as a juggler, magician, and puppeteer. In 1981, the multi-talented youth placed second at the 1981 International Jugglers Competition, leading to a stage career in which he worked with different troupes around the U.S. Dempsey made his feature film debut playing a bit part in Heaven Help Us (1985). This led to his being cast as a regular on the short-lived TV series Fast Times the following year (based upon the movie Fast Times at Ridgemont High ). Dempsey then returned to feature films, where he worked steadily for several years. Although primarily a comic actor, he showed considerable talent for drama in the 1991 film Mobsters , and later received an Emmy nomination for his performance as Sela Ward 's schizophrenic brother on ABC 's Once and Again in 2001. Returning to his comedy roots, he starred as Reese Witherspoon 's big city fiancé in 2002's Sweet Home Alabama.
