Jim Carrey no longer supports the violent content of his latest film, the soon-to-be-released Kick-Ass 2.

The veteran comedic actor expressed his disapproval for the movie because of his sensitivity toward on-screen violence due to the Sandy Hook shootings, which killed 20 children and six adults at a Connecticut elementary school last December.

"I did Kickass a month b4 Sandy Hook and now in all good conscience I cannot support that level of violence," Carrey tweeted on Sunday. "My apologies... to others involve[d] with the film. I am not ashamed of it but recent events have caused a change in my heart."

Mark Miller, one of the film's writers, addressed Carrey's surprising stance in a blog post. The screenwriter said he "respects" the actor's admirable disapproval of gun violence and support for gun control but admitted he was "baffled" by Carrey's announcement because the movie didn't contain any content that wasn't in the screenplay.

Miller also compared the aesthetics of "Kick-Ass 2" to those of films directed by Quentin Tarantino, saying the sequel "avoids the usual bloodless body-count of most big summer pictures."

"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," Miller pointed out.

The screenwriter said he does not believe violence in films leads people to commit real-life acts of violence and he hoped Carrey would rethink his position on the film, but "ultimately" it was the actor's decision.

Carrey has a role in another film set to be released this year in Anchorman: The Legend Continues. It's unknown whether the sequel to Anchorman: The Legend of Ron Burgundy contains any gun violence.

Kick-Ass 2 is set to be released on August 16.
