Yet another ER veteran is coming back to the show for a last-season guest spot.Alex Kingston will reprise her role as Dr. Elizabeth Corday in the January 15 episode. She'll come back when Neela has to interview with her for an attending job. If you remember, Corday was married to Dr. Mark Greene but inevitably had to leave the show after he died and there really wasn't much for her to do (those episodes where she dated others just didn't ring true).
