Sources confirm that Alias' Merrin Dungey and Judging Amy's Amy Brenneman (pictured) have joined the cast of the Grey's Anatomy spin-off (or the potential spin-off, as it's being called, beginning with a special two-hour episode of Grey's scheduled for this spring).
The hiring of this duo puts to rest speculation that Kate Walsh would find herself surrounded by a mostly-male ensemble - buzz that only intensified with the recent casting of stars Tim Daly and Taye Diggs.
We've also confirmed that Paul Adelstein (Prison Break) and Chris Lowell (Veronica Mars) have been added to the cast.
With Shonda Rhimes at the controls and a cast loaded with experienced, successful actors, it seems to us this thing has a pretty good chance of being picked up as a full series. What do you think?
