NEW YORK (AP) — Some of the most promising young filmmakers in the movie business are arriving in Hollywood already experts at entertaining audiences and going viral. The twin sensations of “Obsession” and “Backrooms” — both by 20-something YouTubers-turned-filmmakers — has put a new spotlight on an increasingly well-trod path to the director’s chair. Hollywood executives are scouring platforms like YouTube, TikTok and Instagram to find the next Steven Spielberg. There, young aspiring filmmakers are not only working on their craft but building a relationship with audiences that can transfer to the box office. “These filmmakers are in a dialogue with their audience from the word ‘Go’. Their subscribers have direct input in each iteration of these things,” Mike De Luca, Warner Bros. Motion Picture Group co-chair, said at a conference last month. “By the time you get to the movie, they’ve had a billion test screenings.”“Obsession” and “Backrooms” aren’t the first of their kind. Issa Rae and Bo Burnham are among those who began on YouTube. But more and more of today’s indie filmmakers began online. Here are some of the digital creators who have already broken through, and some who may soon.
