Just like the rest of the nation, Hollywood is not taking last Friday's tragic elementary school shooting in Newtown, CT lightly.

Friday's shooting left 26 people, including 20 children, dead in the school shooting at Sandy Hook Elementary. In response, several networks have pulled upcoming violent episodes before airing, including Syfy's Haven and Fox's Family Guy and American Dad. None of the shows have announced when, or if, they plan on airing the episodes. In addition, the U.S. premieres of the Tom Cruise flick Jack Reacher and Bette Midler comedy Parental Guidance have been postponed out of respect for the victims.
