Her inspiration for the show came from growing up in a theatrical family, and also working as a nanny in New York in the 80s.

She has a love of films set there, such as Taxi Driver, Tootsie and Kramer vs Kramer - although Budapest doubles for the Big Apple's cityscapes in Eric.

No stranger to how the entertainment industry works, the Emmy-winning writer says she gave Netflix a one-line pitch for the show.

"I told them, 'It's about a man who goes on a quest to find his son, and there's a seven-foot blue puppet on his shoulder'."

But much like the melting pot of New York City, Morgan's show is a multi-layered look at issues from addiction, family breakdown and mental illness to homophobia, racism, corruption, homelessness and the Aids epidemic.

"I didn't intend to explore so much at once," she explains. "But if you're going to take on the city at that time, it's pretty hard not to cross over those major themes.

"You know, we still have that dark underbelly in every city in the world. We still have those themes that may have modified with time.

"But they're still there - racism, homophobia, greed, corruption - and so those felt like the sort of the obstacles our characters had to cross over and travel through."
