There are a couple of (arguably) A-List celebrities filming Marley and Me, based on John Grogan's book of the same name, in Center City Philadelphia (Broad and Walnut, to be exact) today. Including this TV hottie. Can you identify this Grey's Anatomy cast member who'd never really take SEPTA but is pretending to for the sake of movie?

If you guessed Eric Dane, you're right!

[You stalker.]

Also in the movie are Owen Wilson and Jennifer Aniston. Phillyist reader Phillybits wrote to let us know he managed to snap some shots of Owen and Eric on set. We'll be sure to update you if we get information about other filming locations. In the meantime, be sure to keep sending us your tips!

(Owen's brother Luke is also on the Main Line filming a movie of his own. If you have tips about the brunette Wilson brother, we'll take those, too.)
