Jim Carrey filmed his role for the upcoming "Kick-Ass 2" a month before the Sandy Hook shootings left 20 children and 6 adults dead from gun violence.

Now the actor says he can't "in good conscience" support the film he helped bring to life.

Yesterday afternoon, Carrey sent off a tweet proclaiming, "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"

Carey later qualified his earlier tweet by saying, "I meant to say my apologies to others involve [sic] with the film. I am not ashamed of it but recent events have caused a change of heart."

As of this writing, Carrey has not deleted, nor tweeted any further on the matter, but that doesn't mean things are settled after his emotionally charged messages.

Kick-Ass 2 is the follow-up to 2010's smash hit, Kick-Ass about a group of kids who dress up as super heroes to battle bad guys. There is some very real violence, but nothing like some other action fare over the blockbuster summer season.

The sequel will be released on August 16 this summer.

One of the film's writers, Mark Miller, wrote about Carrey's change of heart and the ensuing controversy in a long blog post today.

"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 goes on to say that--similar to Quentin Tarantino's movies--Kick-Ass 2 is pure fiction that largely "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 also pointed out.

Miller went on to say he does not believe that on-screen violence leads to real-life violence, and he hopes Carrey changes his mind.

"But, ultimately, it's his decision."

And here's the official Red Band trailer for Kick-Ass 2. You can decide whether it's too violent for Jim Carrey to support, but we can guess his co-stars aren't going to be too happy when they're making the media rounds.
