Jim Carrey isn’t joking around.

The comedic actor withdrew his support for his upcoming film “Kick-Ass 2,” explaining that he can’t stand behind the movie’s violent themes.

“I did Kickass [sic] a month b4 Sandy Hook and now in all good conscience I cannot support that level of violence," he tweeted on Sunday, referring to the shootings that killed 20 children and six adults at a Connecticut elementary school last December.

"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.”

The movie, which will head to theaters this summer, is a sequel to the 2010 flick “Kick-Ass,” based off of a comic book by the same name.

Mark Miller, one of the film’s writers, reacted to Carrey’s sudden declaration in a long blog post about the controversy.

“As you may know, Jim [Carrey] 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,” Miller wrote.

Miller added that—like Quentin Tarantino’s movies—“Kick-Ass 2” is fiction that “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.

Miller added that he does not believe on-screen violence leads to real-life violence.

The writer concluded his message by stating that he hopes Carrey reconsiders his stance but “ultimately, this is his decision.”

The actor has yet to post any other messages about the film.

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