Dermot Mulroney will play the lead opposite Augustus Prew in Bunker Hill, CBS’ medical drama pilot written by Jason Katims and directed by David Semel.

The project follows James Bell (Prew), a young Silicon Valley tech titan who enlists Walter Wallace (Mulroney), a veteran surgeon with a controversial past in starting a hospital with a cutting-edge, “new school” approach to medicine. Wallace is described as a brilliant surgeon committed to saving lives who might care a little too much about his patients. Brenda Song co-stars.

Semel executive produces with True Jack Prods.’ Katims and Michelle Lee for Universal TV and CBS TV Studios.

Mulroney, who has been recurring on Showtime’s Shameless, is repped by WME.
