Family members of a prominent art dealer who was slimed in a 2008 film have settled their differences with the movie’s makers.

Sam Green, who died in March of last year, was portrayed as having a threesome with a New York woman and her son in the 2008 movie “Savage Grace.”

The film, billed as “an incredible true story,” starred Julianne Moore as Barbara Baekeland, a troubled socialite who had a freaky relationship with her schizophrenic son, Tony. The real-life Tony stabbed his mother to death in 1972.

Green acknowledged in court papers he had a relationship with Barbara, but said “at no time . . . did Sam Green engage in ménage à trois.”

Green’s suit charged the movie “induced an evil opinion” of him.

His family continued the suit after his death at age 80, and it was settled last week.
