LOS ANGELES - NBC is pulling the drama series "Do No Harm" after two low-rated episodes. The show is a take on the story of Dr. Jekyll and Mr. Hyde, and stars Steven Pasquale. He plays a respected neurosurgeon who turns into a dangerous alter ego each night. Other cast members include Alana De La Garza and Phylicia Rashad. "Do No Harm" started with a historically small audience for a major network debut and then dropped further in its second Thursday airing.
