A number of high profile Hollywood film premieres have been canceled in response to the recent school shooting in Connecticut. Among them is director Quentin Tarantino's "Django Unchained," a violent spaghetti Western starring Jamie Foxx, Christoph Waltz and Leonardo DiCaprio. A Weinstein Company source said the cancellation was unrelated to the violence depicted in the movie. The film is due to hit U.S. theaters on Christmas Day. Meanwhile, Paramount Pictures canceled the Pittsburgh pemiere of Tom Cruise's new film "Jack Reacher," about a cold-blooded former military sniper. A New York screening and conversation with the actor, arranged by the Lincoln Center Film Society, was also cancelled. "Jack Reacher," which opens with a violent shooting scene, is due to open in U.S. theaters on December 21st. And Fox Studios canceled the weekend premiere of "Parental Guidance," the new comedy starring Billy Crystal and Bette Middler. On television, the Fox broadcast network pulled graphic trailers for its upcoming serial killer drama "The Following," and replaced Sunday episodes of animated shows "Family Guy" and "American Dad" to avoid the airing of any potentially sensitive content. A total of 27 people, 20 of them 6 and 7-year-olds, died in last week's shooting -- the bloodiest attack against children in U.S. history.
