The Fraternal Order of Police, the largest police union in the U.S., said that it has a “surprise” in store for filmmaker Quentin Tarantino, who has drawn the ire of police over his comments last month.

Jim Pasco, the union’s executive director, told The Hollywood Reporter on Thursday that they will be “opportunistic.”

"Tarantino has made a good living out of violence and surprise. Our officers make a living trying to stop violence, but surprise is not out of the question,” Pasco told THR.

Pasco said that a surprise is “in the works,” but wouldn’t give any kind of indication of what it will be. He did say it wasn’t a physical threat, though.

“Something could happen anytime between now and [the premiere]. And a lot of it is going to be driven by Tarantino, who is nothing if not predictable,” Pasco said. “The right time and place will come up and we'll try to hurt him in the only way that seems to matter to him, and that's economically.”

Pasco’s comments come just as Tarantino is trying to clarify his comments made about police at a rally in New York City late last month, when he called police “murderers.” Earlier this week, he told the Los Angeles Times that he doesn’t think all police are murders and that the boycotts of his upcoming film are meant to “intimidate me.”

Tarantino also appeared on MSNBC last night and will be on Real Time with Bill Maher tonight.

The director’s next film, The Hateful Eight, opens in limited release on Dec. 25 before going wide on Jan. 8.
