Actor Mel Gibson — known for past antisemitic behavior — is set to star in an upcoming movie satirizing the Rothschild family, long the subject of antisemitic conspiracy theories.

Gibson’s co-star in “Rothchild” — directed by Jon S. Baird — will be Shia LaBeouf.

Hollywood Reporter described the film as a “black comedy” that focuses on “Becket Rothchild (Shia LaBeouf) — the bastard child of a mother, who in eloping with a jazz musician was cast out from the Rothchild family and its vast fortune — who was never given a fair lot in life.”

Gibson, the report said, will play Becket’s “sinister grandfather,” Whitelaw.

In 2004, Gibson came under fire for his film “The Passion of the Christ,” which suggested Jews were responsible for the crucifixion of Jesus. And during a July 2006 DUI arrest, Gibson yelled at Jewish LA police officer James Mee, “F*** the Jews. The Jews are responsible for starting all the wars in the world.”

Also, Gibson’s father, Hutton Gibson, is a Holocaust denier, and Gibson has not denounced his dad’s views.

Twitter commenters were quick to point out on Monday the problematic nature of Gibson’s role in “Rothchild.”

“‘Mel Gibson is exactly whom we should cast to play a rich Jewish guy whose last name evokes every anti-Semitic trope of last two centuries,’ said the most tone-deaf casting director in Hollywood history,” one tweet mused.

“Who knows, maybe noted anti-semite Mel Gibson will bring a measure of subtlety and nuance to his portrayal of a wealthy Jewish banking scion,” another said.
