Outspoken Moore believes it's shameless for director Brett Ratner to release the film so soon after fellow comic book creator Steve Moore's death.
Moore, no relation, created the Hercules: The Thracian War comic series, which inspired the new movie. He died earlier this year (Mar14).
Alan Moore tells BleedingCool.com, "I would ask that anybody out there who gives a damn about Steve Moore or his legacy not go to see this wretched film. It is the last thing that Steve would've wanted. And I cannot un-recommend it too highly or anybody involved in it. I think it is absolutely shameful... There are also more positive elements of Steve's legacy."
Moore claims his namesake found out about plans to turn his comic books into a movie a few months before his death.
He says, "(He told me), 'I've just written them (comic book bosses) an angry email asking why I wasn't consulted in this and when I can expect the something like $15,000... I haven't heard back from them. There's just a deafening silence."
According to CinemaBlend.com, Steve Moore's contract with Radical Comics bosses, who sold the film rights, made it clear he would have no involvement or money if a movie adaptation of his comics was made.
Alan Moore adds, "The only consolation was that his name wouldn't be going on it."
