Actor Jim Carrey took to Twitter on Sunday to denounce the violence of his upcoming movie Kick-Ass 2 , wherein he plays the costumed vigilante Colonel Stars and Stripes.

"I did Kickass a month b4 Sandy Hook and now in all good conscience I cannot support that level of violence," tweeted Carrey.He added , "(My) apologies to others involve with the film. I am not ashamed of it but recent events have caused a change in my heart.""As you may know, Jim is a passionate advocate of gun-control and I respect both his politics and his opinion, but I'm baffled by this sudden announcement as nothing seen in this picture wasn't in the screenplay eighteen months ago. Yes, the body-count is very high, but a movie called Kick-Ass 2 really has to do what it says on the tin. A sequel to the picture that gave us HIT-GIRL was always going to have some blood on the floor and this should have been no shock to a guy who enjoyed the first movie so much. My books are very hardcore, but the movies are adapted for a more mainstream audience and if you loved the tone of the first picture you're going to eat this up with a big, giant spoon. Like Jim, I'm horrified by real-life violence (even though I'm Scottish), but Kick-Ass 2 isn't a documentary. No actors were harmed in the making of this production! This is fiction and like Tarantino and Peckinpah, Scorcese and Eastwood, John Boorman, Oliver Stone and Chan-Wook Park, Kick-Ass avoids the usual bloodless body-count of most big summer pictures and focuses instead of the CONSEQUENCES of violence, whether it's the ramifications for friends and family or, as we saw in the first movie, Kick-Ass spending six months in hospital after his first street altercation. Ironically, Jim's character in Kick-Ass 2 is a Born-Again Christian and the big deal we made of the fact that he refuses to fire a gun is something he told us attracted him to the role in the first place. Ultimately, this is his decision, but I've never quite bought the notion that violence in fiction leads to violence in real-life any more than Harry Potter casting a spell creates more Boy Wizards in real-life. ... Jim, I love ya and I hope you reconsider for all the above points. You're amazing in this insanely fun picture and I'm very proud of what Jeff, Matthew and all the team have done here."Kick-Ass 2 opens August 16.
