Rachel Returns to 'One Tree Hill'

"One Tree Hill" is shaping up to be the next "Beverly Hills, 90210."

Sure, on-screen "Tree Hill" follows a group of friends from high school to post-college and tackles the same angst storylines -- but that's not what were talking about.

We're referring to the behind-the-scenes shuffling of main players, and today's announcement of Danneel Harris' return for a seven-episode arc is just the icing on the character cake.

By following "Beverly Hills" revolving-door casting policy, the seven-year and running "Tree Hill" has the potential to remain on air for years to come by reinventing its cast and introducing new storylines.
