‘Do No Harm’ and ‘Zero Hour’ to Finish Out Their Seasons on Saturdays This Summer April 29, 2013 Do No Harm, News NBC’s Do No Harm and ABC’s Zero Hour were yanked from the airwaves due to low ratings earlier this season, but both series will be back to finish out their runs this summer. Do No Harm, which starred Steven Pasquale as a modern day Dr. Jekyll and Mr. Hyde, will return to NBC’s lineup Saturday, June 29th at 10/9c, as reported by The Futon Critic. Meanwhile, The Futon Critic also revealed that ABC’s Da Vinci Code-style conspiracy theory drama Zero Hour will resurface Saturday, June 15th at 8/7c leading up to a two-hour finale on August 3rd. Those who were left hanging by the spooky goings-on at ABC’s 666 Park Avenue might also be in luck. Although no airdate has been confirmed, TV Line is reporting ABC has plans to burn off the remaining episodes of the Terry O’Quinn and Vanessa Williams-led drama beginning sometime in June.
