Three more actors are heading Inside the Box, the ABC pilot penned by Richard Robbins and exec-produced by Grey's Anatomy's Shonda Rhimes and Betsy Beers.

Set at a Washington network news bureau and revolving around Caroline, an ambitious female reporter, Inside the Box will feature Everwood alum (and recent Private Practice guest star) Sarah Drew as an entry-level employee, while Jason George (Eli Stone) has been cast as an on-camera correspondent.

Additionally, Brit Lloyd Owen (Viva Laughlin) has landed the role of the retiring bureau chief's replacement, says the Hollywood Reporter.

As previously announced, New Zealander Martin Henderson has been tapped for the male lead, playing the "McDreamy" to the as-yet-uncast Caroline.
