ER is bringing on a quartet of new recurring players for its final season - all of them playing interns at County General.

According to the Reporter, Shiri Appleby ( Roswell) and Julian Morris have been cast as siblings (she's smart, he tries to skate by on looks alone), Emily Rose ( Brothers & Sisters) will play a controlling type who (all together now) rubs folks the wrong way, and Victor Rasuk's character is a native New Yorker henpecked by his wife. - Matt Mitovich
