at .  Updated at .

Grey's Anatomy has been on for so long, it's hard to even remember TV without it, but where were its cast members before they started working at Grey Sloan Memorial Hospital?

All over the map!

With a cast this large, diverse and varied in age - Shonda Rhimes' calling card and blueprint for so much success - we get to see a lot of different stories.

The Grey's Anatomy cast has starred with the likes of Susan Sarandon, Jake Gyllenhall, Vince Vaughn. Ewan McGregor, Meg Ryan and Tom Hanks! 

The men and women we love have played daughters, drug addicts, doctors, lovers, cashiers, policemen and many other roles before getting their M.D.'s on ABC.

If you can match the star to the parts, good for you. Bonus round for those who know which stars guest-starred on the same shows over the years!
