Jim Carrey tweeted this week that he couldn’t support his movie Kick-Ass 2 anymore after a change of heart, but did he violate his contract in doing so?

Carrey wrote, “I did Kickass a month b4 Sandy Hook and now in all good conscience I cannot support that level of violence,” adding, “I meant to say my apologies to others involve with the film. I am not ashamed of it but recent events have caused a change in my heart.”

The movie doesn’t come out until Aug. 16, and Mark Millar, whose comic book series the movies are based on, has responded, saying he is “baffled by this sudden announcement as nothing seen in this picture wasn't in the screenplay eighteen months ago.”

Experts tell FOX that he could’ve violated a publicity clause in his contract, but it “likely won’t turn into much more than a wrist slap,” an insider says.

Producer Gary Michael Walters said of the importance of actors promoting their films, “Publicity, promotion and marketing are just as important to the success of a film as the quality of the film itself, and it is crucial for a distributor to tightly control all aspects of the branding and imaging of the film.”

Universal could technically sue Carrey for breaking the clause of not saying anything negative about the film, but as an insider notes, studios “generally don’t make it a habit to sue A-list celebrities.”
