James Cromwell Joins Cast of NBC's New Drama DO NO HARM

TVline reports exclusively that James Cromwell has joined the cast of the new NBC drama series DO NO HARM, premiering Thursday, January 31 at 10/9c. It had earlier been revealed that the actor would guest star on the show, but according to the report, he will now take on a 'pivotal role' in the thriller.

David Schulner, the show's executive producer, reveals Cromwell will appear as "Jason's (Steven Pasquale) mentor, "who may or may not have his best interests at heart."

Cromwell was recently seen on the big screen in last year's Academy Award winning film, The Artist. He currently stars in the FX drama series 'American Horror Story.'

In DO NO HARM, Dr. Jason Cole (Steven Pasquale, "Rescue Me") is a highly respected neurosurgeon who has it all - a lucrative career, confident charm, the gift of compassion. But he also has a deep, dark secret. One morning when he wakes up disoriented in a wrecked hotel room amidst several near-naked women he's never seen before, he knows one thing: it's happening again. Every night at the same hour, something inside Jason changes, leaving him almost unrecognizable - seductive, devious, borderline sociopathic. This new man is his dangerous alternate personality who goes by the name of 'Ian Price.' For years he's battled Ian, keeping him in check with a powerful experimental sedative. But now his - their - body has developed a resistance to the serum, setting Ian free once again. And to make matters worse, after being suppressed for so long, Ian is hell-bent on taking Revenge on his oppressor. With everyone Jason cares about at risk - patients, friends, coworkers and even the woman he loves - he's got to stop Ian once and for all. Will they find some common ground, or will they bring each other down? Hell hath no fury like an alter ego scorned.

"Do No Harm" is produced by Universal Television and Traugott Company. The executive producer/writer is David Schulner ("Desperate Housewives," "The Event"). Peter Traugott ("Ringer") and Rachel Kaplan ("Ringer") also are executive producers. Michael Mayer (NBC's "Smash") is the co-executive producer and director.
