Fox news commentator Bill O’Reilly warned Quentin Tarantino that his career has been “ruined” after the Hollywood director attended a protest against police brutality in New York City.

Tarantino spoke out against the fragile relationship between police officers and civilians following a number of shootings in the US, but critics attacked him for speaking out after building a career off the back of incredibly violent films such as Pulp Fiction and Django Unchained.

He said the police and the public’s discord is “not being dealt with in any way at all” and urged “murdering cops” to be sent to jail.

But the rally, organised by the group RiseUpOctober, was criticised for the “unfortunate timing” that saw the anti-police protest occur shortly after a US police officer was shot dead in East Harlem.

O’Reilly said "This Tarantino character, I think he destroyed his career, because anybody hearing [him is] going to think: 'You know what? Maybe I’m not going to see his movies'."

He added that Tarantino "lives in a world of his own" and that his condemnation was "demoralising" many police officers.

"[The] facts don’t matter. He has no problem spreading big lies."

Tarantino’s appearance has also angered the New York police, who have suggested boycotting his films.

“The police officers that Quentin Tarantino calls ‘murderers’ aren’t living in one of his depraved big-screen fantasies — they’re risking and sometimes sacrificing their lives to protect communities from real crime and mayhem," said Patrick Lynch, president of the Patrolman's Benevolent Association.

“New Yorkers need to send a message to this purveyor of degeneracy that he has no business coming to our city to peddle his slanderous 'Cop Fiction.'"
