Grey's Anatomy Cast: Where Are the Ex-Stars Now? (PHOTOS)

Any show that has lasted as long as Grey's Anatomy has its fair share of former cast members. From memorable guest stars killed off too soon to beloved regulars who had to leave, Seattle Grace-Mercy West has said goodbye to many talented faces over the years.

While these actors may be gone from the Grey's universe, they're still alive and working in the real world, and there are still plenty of ways to catch them in action. Some have moved onto movies, and many are still rocking it on the small screen.

Since Grey's is between seasons right now, we've taken the time off to gather info on where many of our old favorites are these days. You can fill the free time between now and the new season of Grey's with these shows and movies.

So click through this gallery to find out what happened to T.R. Knight (George O'Malley), Jeffrey Dean Morgan (Denny Duquette), Brooke Smith (Erica Hahn), Katherine Heigl (Izzie Stevens), and many more.
