As police unions around the country are vowing to boycott Quentin Tarantino's new movie, The Hateful Eight, Jamie Foxx is defending comments the director made about police brutality.

"Keep telling the truth, keep speaking the truth and don't worry about none of the haters," Foxx, who starred in Tarantino's 2012 film Django Unchained, said as he was presenting an ensemble award to the cast of The Hateful Eight, according to The Hollywood Reporter. (Tarantino did not attend the awards show.)

Tarantino has come under fire for comments he made at an anti-police brutality rally that was held in Manhattan on Oct. 24. Tarantino made a speech there in which he said, "I have to call a murder a murder and I have to call the murderers the murderers."

In the wake of his remarks, police unions in cities including Chicago, Philadelphia, Los Angeles and New York, as well as the National Association of Police Organizations (which collectively represents 1,000 police units and nearly 250,000 individual officers) are urging people to boycott The Hateful Eight and Tarantino's other films.

On Sunday, TheWrap reported that Tarantino is expected to speak out about the proposed boycott in an opinion piece, and intends to apologize for his comments about police officers.

The Hateful Eight, which is set in post-Civil War Wyoming and stars Samuel L. Jackson, Jennifer Jason Leigh and Kurt Russell, hits select theaters on Christmas Day and will open wide in January.
