Don’t expect Jim Carrey to appear on any red carpet premiere of his new movie “Kick-Ass 2.” The comedian, who plays Colonel Stars and Stripes in the kiddie/teen superhero action movie, cited the gruesome Sandy Hook elementary school massacre as basis for calling his new film too violent.

Carrey, 51, was announced in September last year to join the highly anticipated sequel of the 2010 blockbuster hit. In the film, which brings back the first film’s stars Aaron Johnson and Chloe Grace Moretz, he plays the leader of a group of superheroes called Justice Forever.

The film was about a group of ordinary kids who dressed up in superhero costumes to fight the bad guys. The film had been cited for its extreme violence, with the Australian Family Association even condemning it for having offensive language and inappropriate values.

Nevertheless, it was a commercial success, grossing almost $100,000 in the theatres in 2010.

For the second film, fans are still expecting violence, and judging by the trailer, it would not disappoint them.

But for Carrey, that’s exactly why he has had a change of heart.

“I did Kickass a month b4 Sandy Hook and now in all good conscience I cannot support that level of violence,” the star tweeted on Monday.

“My apologies to others involved with the film. I am not ashamed of it but recent events have caused a change in my heart.”

The Sandy Hook Elementary School shooting occurred in December of last year when Adam Lanza fatally shot 20 children and six adult staff members in the Connecticut elementary school. The shocked the whole U.S. nation and the rest of the world were shocked by the horrific mass killing tragedy, especially since the children victims were all first graders.

Meanwhile, “Kick-Ass 2” comic book creator Mark Millar was “baffled” by Carrey’s sudden announcement.

“Like Him, 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...” he wrote on his forum.

“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.

“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.”

“Superman just snapped a guy’s f****** neck,” he added as a point.

Still, Millar hopes that Carrey reconsiders his position, “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.”
