Actor Jim Carrey has withdrawn his support for his new movie Kick-Ass 2 over fears the "level of violence" in the film is inappropriate in the aftermath of December's (12) Connecticut school massacre. The Mask star plays a vigilante named Colonel Stars and Stripes in the follow-up to Matthew Vaughn's 2010 hit and he filmed his scenes for the sequel last November (12). Just weeks after Carrey wrapped his work on the movie, 20 children and six adults were killed by a gunman at Sandy Hook Elementary School, and the headline-hitting atrocity made the actor rethink his commitment to the project. In a post on his Twitter.com page on Sunday (23Jun13), he told fans, "I did Kickass (sic) a month b4 (before) Sandy Hook and now in all good conscience I cannot support that level of violence. "My apologies to others involve (sic) with the film. I am not ashamed of it but recent events have caused a change in my heart." Kick-Ass 2, directed by Jeff Wadlow and starring Aaron Taylor-Johnson and Chloe Grace Moretz, is set for release in August (13).
