LOS ANGELES — A gnarled buffalo hide hangs inside “the barn,” a cavernous room furnished with sofas and long tables. A secret passageway leads to an old-fashioned saloon where whiskey bottles line the wooden shelves and the bar stools are actual saddles. Antlers and antique rifles adorn the walls.

A cowboy maxim greets visitors: “Everybody in. Everybody forward. Everybody up.”

This is Rideback Ranch and, in some ways, it feels like a movie set, perhaps one built for Leonardo DiCaprio’s Old West scenes in “Once Upon a Time … in Hollywood.” But the two-year-old complex in a gentrifying area of Los Angeles called Filipinotown is actually an attempt by one of the entertainment industry’s leading producers, Dan Lin, to find a new way to develop ideas for movies and TV shows.

Rideback is a communal work space for Hollywood writers and producers. Mr. Lin calls it “a new kind of production hub — a community in service of creativity.”

His credits include blockbusters like “Aladdin,” “It” and “The Lego Movie.” He was the producing force behind “The Two Popes,” a $40 million comedic drama about Vatican succession that arrives on Netflix on Friday. “The Two Popes,” nominated for four Golden Globes, including one for best drama, is expected to be a major contender at the Academy Awards.
