Eric Roberts joins ABC 'Grace' pilot

Eric Roberts has joined the cast of ABC drama pilot Grace.

The project, from Grey's Anatomy writer Krista Vernoff, will focus on a dysfunctional family immersed in the world of professional dance.

Entertainment Weekly reports that Expendables star Roberts will play father Michael Grace.

The actor, brother to Hollywood star Julia, recently played Vance Abrams on CBS soap opera The Young and the Restless and has also appeared in episodes of Chuck and Heroes.

So You Think You Can Dance judge Mia Michaels will serve as choreographer on the Grace pilot, which is under consideration for ABC's 2011-12 television season.
