Arriving at Charlie's in 2016, the pair found themselves in the thick of Hollywood. "Such a beautiful space, we were a bit shocked," Bell says. "We were used to working from our kitchen tables. [Working in an office] transforms the discipline and the routine of how you work."

The Letdown, about a new mother adapting to the changes in her life, was developed with the ABC's head of drama Rick Kalowski, who commissioned a pilot for the Comedy Showcase program strand. That pilot gave Scheller and Bell something tangible to present to Netflix.

The Charlie's premises, designed by Ingrid Weir, are in the Charlie Chaplin building on the four-hectare Raleigh Studios lot, named for the early years of the studio, when Chaplin and Douglas Fairbanks had offices there. Among the lot's most famous credits are The Adventures of Superman, What Ever Happened to Baby Jane? and, more recently, The Larry Sanders Show.

Since opening, Charlie's has had a stream of Australian writers and producers using the space, including Lion producer Angie Fielder, who worked there during the film's US release and Oscar campaign, screenwriter Harry Cripps, who wrote the script The Dry at Charlie's, and Oscar-nominated actor/writer/producer Josh Lawson.

But The Letdown's launch on Netflix is a particularly significant milestone, not just for Bell and Scheller but for Charlie's, which marked the triumph of its first child with a screening of the pilot in the Chaplin Theatre in Los Angeles this week.

Australians in Film executive director Peter Ritchie sees the show's success as a full circle for the Charlie's mission: to "create a workspace and a community of supportive screen content makers who wish to collaborate and work in the international screen industry".

Even more daunting: Netflix now carries the show, with Bell and Scheller's names, and Bell's performance as Audrey, into close to 190 countries and territories around the world.

But the pair take the scale of Netflix's reach with a grain of salt. "It's incredibly exciting but we're always cautious with everything, we don't get too swept up in it," Scheller says.

Adds Bell, "Our mantra has always been, this could mean something or nothing".

"We feel a bit sick, a bit giddy," Bell said. "It's really thrilling. And it's kind of wild. I don't think either of us ever imagined this seven years ago when we were sitting in [Sarah's] kitchen."
