Christine Lahti Christine Lahti

The doctor is in, again. Christine Lahti, an Emmy winner and overall four-time nominee during her 1990s run on CBS' Chicago Hope, has been added to the cast of the USA Network pilot Operating Instructions.

Lahti will play Commander Helen Keller (Hmm, I can see that...), the chief administrator of a military hospital. Keller instantly and frequently will butt heads with new surgical staff member Lt. Rachel Scott (played by series lead/former Brothers & Sisters bad girl Emily Rose), a Marine just back from a tour in Iraq.

Other recent cast additions to Operating Instructions include Johnny Sneed (Unhitched) as Capt. Will McKay, Nick Zano (What I Like about You) and Diana-Maria Riva (Side Order of Life).
