A German-Jewish comedy: Sounds crazy, no? But “Go for Zucker” is just that: a comedy about two Berlin brothers – one pious, the other a playboy – who reunite to reap an inheritance.

Making it wasn’t easy, writer-director Dani Levy tells The Post.

“It was extremely hard to get people to support this movie,” says Levy, a Jew who – to his mother’s chagrin – moved to Berlin in 1980.

Since the ’60s, he says, “Every time you saw a Jew in a German movie, he was a victim. . . . I felt we needed a new generation of films that portray Jewish life in a modern way, so that people will accept us.”

Born in Switzerland 48 years ago – his mother fled Nazi Germany at age 11 – Levy followed a theater troupe to Berlin and fell in love with the “grotesque and original way of life” in a city divided by a wall.

But while he became a founder of a successful production company (creating films such as “Run Lola Run”), it took him six or seven years to come up with the money – and the blessing – to shoot “Go for Zucker.”

“We’re really afraid of making movies about minorities,” the Germans told him.

“You’ll only create problems for yourself,” said his mother.

Eventually, he won them over – securing permission to shoot in a synagogue and a Jewish cemetery, and turning out the film in 23 days. “Zucker” snagged several German film awards and became one of the few “ethnic films” to become a box-office hit.

Only in Israel, Levy says, was it considered controversial.

“There were two big newspapers that attacked the movie for using Nazi propaganda – the fat mama, the gay son, the interest in money,” he says.

“I told them, ‘That’s your perspective. I don’t want to define my Jewish life by Nazi clichés. . . . There’s no reason a Jewish family can’t have the same problems any other family can have.’ ”

And his mother?

She loved it, he says. “She was relieved that the characters were sympathetic and lovable and positive.”
