Jim Carrey has launched a surprising attack on his own film, taking to Twitter to condemn the level of violence in Kick-Ass 2 and make his intentions clear to avoid promoting the film. The outspoken actor explains his dramatic change of heart by reference to the Sandy Hook tragedy.

Carrey plays a born again Christian superhero in the sequel called Colonel Stars and Stripes. While some have supported his decision, others including Kick-Ass creator Mark Millar have been swift to issue angry rebuttals. You can read below in full Millar’s open letter responding to Carrey’s very public attack on the project.

“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. Our job as storytellers is to entertain and our toolbox can’t be sabotaged by curtailing the use of guns in an action-movie. Imagine a John Wayne picture where he wasn’t packing or a Rocky movie where Stallone wasn’t punching someone repeatedly in the face. Our audience is smart enough to know they’re all pretending and we should instead just sit back and enjoy the serotonin release of seeing bad guys meeting bad ends as much as we enjoyed seeing the Death Star exploding.

The action in Kick-Ass 2 is like nothing you’ve ever seen before. The humour, the characters, the heart and the set-pieces are all things we’re very proud of and the only warning I’d really include is that it’s almost TOO EXCITING. Kick-Ass 2 is fictional fun so let’s focus our ire instead of the real-life violence going on in the world like the war in Afghanistan, the alarming tension in Syria right now and the fact that Superman just snapped a guy’s fucking neck.”

Ironically in announcing his refusal to promote Kick-Ass 2, Jim Carey has  inadvertently promoted it  so much more than if he’d actually just happily been trying to promote it normally in the first place.
