Eight years as an ER surgeon may have been tough on Eriq La Salle — but it will be a cakewalk compared to life Under the Dome.

The TV vet has joined the Season 3 cast of CBS’ sci-fi drama, EW.com reports.

La Salle will play Hektor Martin, a cutthroat CEO of the energy company run by Barbie’s (Mike Vogel) father. He previously directed a Season 2 episode, “The Fall,” and will get behind the camera again for Season 3’s ninth episode.

Since ending his run as ER‘s Dr. Peter Benton, La Salle has appeared on 24, Covert Affairs and A Gifted Man.

Under the Dome Season 3 bows Thursday, June 25 at 9/8c.
