NEW YORK — Hanni Levy’s incredible life isn’t just like a movie — it inspired one, which opens Friday, called “The Invisibles.”

Claus Rafle’s docudrama spotlights four Berlin Jews who survived World War II in the very capital that the notorious Nazi propaganda minister Joseph Goebbels famously boasted had “eliminated all Jews.”

That was hardly true. “Actually there were 7,000 there that were illegally underground,” said producer-director Rafle. “Only 1,500 survived. It was very dangerous. For young men especially — every able young man should be at the front.”

Levy was just 15 in 1939 when war began. Her parents had died, she was alone.

Speaking in German with an English translator at the Arthouse Hotel, the now 94-year-old Levy recalled how an injured finger at her factory job saved her life.

She was at the doctor’s when a Gestapo raid on her apartment building rounded up every Jewish resident for transport to the concentration camps.

This isolated teenager had to learn how to stay alive. “I relied on my instinct and will to live,” she said.

A crucial moment came when, still in her empty apartment, the Gestapo knocked at the door.

Against her instincts she stayed still and didn’t respond. Once they left, Hanni knew she had to leave. “I stayed inside during the daylight and snuck out in the darkness,” when she took the subway to friends of her parents.

“They were already hiding someone and I could not stay there.”

They did find her a hairdresser who transformed Hanni into a blonde so she could walk around Berlin looking like a Nazi-approved Aryan.

They also found someone to take her in — but she had no papers.

“I was fearful, lots of fears, but could never express this because if you’re afraid, you become insecure and people notice something’s wrong.

“So even though I had no papers, I had to go outside and be a normal Berliner.”

Eventually, by going often to the movies (“The movie theater felt like a very safe place.”), she was asked by the cinema manager if she would look after his aged mother — he was being called to the front.

“I never revealed myself to this woman. But I realized she was married to a much older man and neither of them liked Hitler. So I felt safe.”

In 1946 Levy moved to Paris, married and has two children.
