Jim Carrey had a change of heart regarding his upcoming movie Kick Ass 2.



Instead of promoting the film, the actor has condemned its violence in a series of tweets to his over 10 million followers.

I meant to say my apologies to others involve with the film. I am not ashamed of it but recent events have caused a change in my heart. — Jim Carrey (@JimCarrey) June 23, 2013

I did Kickass a month b4 Sandy Hook and now in all good conscience I cannot support that level of violence. My apologies to e — Jim Carrey (@JimCarrey) June 23, 2013



In the movie Carrey plays Colonel Stars and Stripes, a former Mob henchman turned masked super hero/Born Again Christian who fights crime with his faithful yet brutal dog Sophia.



The Kick Ass movies are based on a comic book series by Mark Millar, featuring a teen turned superhero named Kick-Ass and young crime fighter Hit Girl.



The first instalment, featuring a 11-year-old Chloe Moretz as Hit Girl using the c-word, was rated R18 because of its graphic violence, drug use and offensive language.



The baffled author responded to Carrey's comments on his own website. "Carrey is an actor like no other, an unpredictable force of nature who brings a layered warmth and humanity to his work as well as that unstoppable energy he's always been renowned for," Millar wrote.



"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," Millar wrote.



"Yes, the body-count is very high, but a movie called Kick-Ass 2 really has to do what it says on the tin."



"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!"



He adds that it was ironic that Carrey's character in Kick-Ass 2 was a Born-Again Christian and he made a big deal of the fact that he refused to fire a gun, which was something that attracted the actor 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."
