So this is possibly the strangest news story we've seen in a while.
Kick-Ass 2 star Jim Carrey has withdrawn his support from the movie after last year's shooting at Sandy Hook elementary school.
The actor has said he won't do any publicity to promote the film ahead of its release in August, explaining that the incident has changed his opinion on the film's violent content.
He tweeted: "I did Kickass a month b4 Sandy Hook and now in all good conscience I cannot support that level of violence.
"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 in my heart."
Universal Pictures has yet to comment on Carrey's decision, but executive producer and comic book creator Mark Millar has said he's "baffled" by it.
Millar posted on his forum: "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. 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.
"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."
Millar described Carrey's turn as Stars and Stripes as one of his "best-ever performances" and concluded his forum post by asking the star to reconsider his stance.
Twitter, meanwhile, is calling for the actor to dedicate his fee for the film to charity.
Kick-Ass 2 is released in the UK on August 14 and August 16 in the US.
