Hannibal (10pm, NBC) - At the request of the show's creator, Bryan Fuller, NBC is pulling the fourth episode of "Hannibal" due to the "cultural climate" in the country (Newtown, Boston, etc.). The episode, which will not air in the U.S., was about a woman (played by Molly Shannon) who brainwashed children to kill other children. NBC is releasing a series of 'Hannibal' webisodes online that will fill in any holes in character development, particularly between therapist Dr. Hannibal Lecter (Mads Mikkelsen) and Abigail Hobbs, daughter of serial killer Garrett Jacob Hobbs. The episode airing tonight, Episode 5, isn't exactly a picnic in the park. Will (Hugh Dancy, right) and the FBI track a religious serial killer whose ritual includes cutting the victims' back flesh and stretching it out to resemble wings.
