The Oscar-winning director hit headlines after he took to the streets of New York City to join protests against alleged mistreatment of suspects in police custody, and he was reported to have branded cops "murderers" in a speech.

His reported remarks sparked outrage among police officials, but Tarantino has since spoken out to insist his remarks were misunderstood.

"All cops are not murderers. I never said that. I never even implied that," he told the Los Angeles Times.

Police union bosses across the U.S. have urged cops to boycott Tarantino's work, and now the head of America's Fraternal Order of Police, a fraternity body which boasts more than 325,000 members, has gone public with plans to interrupt the premiere of his new film.

James Pasco, executive director of the Fraternal Order of Police, has revealed members of the organisation are planning to show their distaste for the director when he unveils The Hateful Eight, which is due for release in January (16).

"What we do... is going to depend in large part on what Tarantino does between now and then," Pasco tells the New York Post. "We don't want to prepare him. We want what we do to him to be a surprise, like the end of his movies. We will be opportunistic, we will take every opportunity to hurt him in the only area that seems to matter to him and that's in the economic area."
