Laura San Giacomo is joining Holly Hunter in the drama, Grace for TNT.

Leon Rippy and Bokeem Woodbine are also part of the show that centers on a jaded Oklahoma City police detective (Hunter) who is visited by an irascible angel (Rippy) and offered an opportunity to redeem her life. The Hollywood Reporter says San Giacomo will play Grace's best friend, a forensic scientist; Woodbine will play a death-row inmate who also can see the angel.

Grace is set for a 2007 airdate on TNT.
