Mark Millar, the guy who co-wrote the comics and executive produces the movies, responded on his blog, praising Carrey's work in the film and pointing out that he was such a huge fan of the first Kick-Ass, he sang about it during an on-stage appearance with Conan O'Brien.

"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. Yes, the body-count is very high, but a movie called Kick-Ass 2 really has to do what it says on the tin," Millar writes. "A sequel to the picture that gave us HIT-GIRL was always going to have some blood on the floor and this should have been no shock to a guy who enjoyed the first movie so much. My books are very hardcore, but the movies are adapted for a more mainstream audience and if you loved the tone of the first picture you're going to eat this up with a big, giant spoon. 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!"

Millar adds that Carrey's character is actually a born-again Christian and doesn't fire a gun, something that Carrey noted in a tweet to a fan, as well.
