It's a McDream Team! Grey's Anatomy stars Patrick Dempsey and Eric Dane have both joined the ensemble comedy Valentine's Day, according to Movie Fanatic.

They are joining a cast that will include Julia Roberts, Anne Hathaway, Jessica Alba, Jessica Biel, Jennifer Garner, Shirley MacLaine, Bradley Cooper, Ashton Kutcher, Topher Grace, Emma Roberts and Hector Elizondo (who plays Callie's dad on Grey's Anatomy).

Garry Marshall is directing the New Line film for a February 12, 2010 release.

The upcoming movie, which began shooting this week, follows five slightly interconnecting stories playing out in Los Angeles during (of course) Valentine's Day.

Patrick Dempsey will play a married obstetrician (not a neurosurgeon) dating Jennifer Garner's character on the sly, with her unaware of his marital status.

Eric Dane will play a quarterback struggling over the decision of whether to retire from football. Sounds like a quality film - how can it not be with these two?
