Nick Vallelonga, the screenwriter of the new film “Green Book,” apologized Thursday for a 2015 anti-Muslim tweet that recently resurfaced.

“I want to apologize. I spent my life trying to bring this story of overcoming differences and finding common ground to the screen, and I am incredibly sorry to everyone associated with ‘Green Book’,” he said in a statement. “I especially deeply apologize to the brilliant and kind Mahershala Ali, and all members of the Muslim faith, for the hurt I have caused. I am also sorry to my late father who changed so much from Dr. Shirley’s friendship and I promise this lesson is not lost on me. ‘Green Book’ is a story about love, acceptance and overcoming barriers, and I will do better.”

In the controversial tweet, Vallelonga agreed with President Trump’s debunked claim that “thousands” of Muslims in New Jersey cheered and celebrated on Sept. 11, 2001.

“@realDonaldTrump 100% correct,” the tweet read. “Muslims in New Jersey cheering when towers went down. I saw it, as you did, possibly on local CBS news.”

Participant Media, which co-produced “Green Book,” also denounced the tweet in a statement.

“We find Mr. Vallelonga’s Twitter post offensive, dangerous, and antithetical to Participant Media’s values. We reject it in no uncertain terms,” a spokesman said.

Following the backlash, Vallelonga deleted his Twitter account Wednesday.

The scrutiny comes in the wake of the film — which is based on the life of Vallelonga’s father, “Sopranos” actor Tony Lip — winning three Golden Globe Awards Sunday night. Those included Best Motion Picture (comedy), Best Supporting Actor (Mahershala Ali) and Best Screenplay.
