Cast (ABC)

One of the most intense and disturbing season finales in recent television history caps this collection of recent episodes from the ABC medical drama.

As usual, the personal and professional lives of the doctors of Seattle Grace are in flux ... but arguably never more so than when a vengeful gunman invades the hospital in that gripping climactic story, which features guest star Mandy Moore. Kim Raver ( "24") joins the regular cast here. DVD extras: deleted scenes; outtakes; profile of Chandra Wilson; extended version of season finale. *** (Not rated: AS, P, V)
