She'll be playing a new intern, Dr. Julia Wise, in the April 2 episode.
Alexis is the latest guest to join the medical drama's final season – Susan Sarandon and returning "ER" alumna Julianna Margulies will be appearing in the show's March 12 episode. George Clooney, who filmed his "ER" comeback this past January on the Warner Bros. lot in Los Angeles, is rumored to be appearing in the March 12 episode as well.
