“I thought, ‘All right. Not a problem.’ My dad talks Moroccan, which is Arabic. I was like, ‘Alright, Moroccan, Farsi — probably going to be similar.’ No! It has nothing to do with Hebrew and not with Arabic. The pronunciation is so, so difficult for a Hebrew speaker.”

Zonder — who served as a head writer on the first season of “Fauda,” the groundbreaking action series on the Israeli-Palestinian conflict — spent years researching and writing “Tehran.”

The two series share an attempt to humanize enemies. In ”Fauda,” Zonder showed how a Hamas leader with Israeli blood on his hands was also a family man, much like he does with the main Iranian security officer chasing the heroine in “Tehran.”

Zonder said he reached back to his days as an investigative journalist when he would sit down with Hamas and PLO leaders and interview them to understand their point of view.

“I always want to cross borders — physically and mentally — in order to meet the one that I’ve been told all my life is my enemy,” he said.

While today Iran and Israel are mortal enemies, the series teases out their shared history and the respect Israelis and Iranians had for each others’ cultures before the Islamic Revolution.

“It’s an amazing country. They have an amazing nature and views and food. Hopefully, some day, I could go to visit Iran and Tehran,” said Sultan. “But for now, I’m focusing on the possibility that maybe our series will open peoples’ hearts and maybe open up some dialogue between Israelis and Iranians.”
