ER will have four new cast members when the show returns for its final season this fall. Shiri Appleby, Julian Morris, Emily Rose and Victor Rasuk will all join the cast of ER as new interns.

Shiri Appleby and Julian Morris will play siblings Daria and Andrew Wade. Emily Rose will play ambitious intern Tracy Martin, while Victor Rasuk will play nervous intern Ryan Sanchez.

Executive producer David Zabel said of the ER casting news: “The new group of young characters — played by four charming and singular actors — adds a burst of fresh energy and a bunch of different personalities for us to play off of as we enter our 15th and final season. So while we will be reconnecting with the history of ‘ER,’ as well as telling the ongoing stories of our current regulars, we also will track the development of these new young doctors.”
