For years, Quentin Tarantino has maintained his goal to retire from filmmaking after directing 10 movies. His most recent opus, Once Upon a Time in Hollywood, was his ninth writer-director credit (if Kill Bill only counts as one movie), so his next film could be his last. Considering how consistently entertaining and successful his movies are, this decision has baffled some fans. But Tarantino wants to avoid the mistake that most popular directors make. Just because studios will keep financing movie after movie from them, it doesn’t mean they have anything left to say.
