The day John Lennon was shot in 1980, he and Yoko Ono gave an interview to a San Francisco radio crew from their home in New York’s Dakota Apartments. In “John Lennon: The Last Interview,” Steven Soderbergh pp those surviving tapes into a new documentary that debuted Saturday at the Cannes Film Festival. But his decision to fill in some visuals using Meta's AI software has prompted an outcry. One of America’s leading filmmakers was using AI? In a film about a Beatle, no less? Soderbergh has placed himself at the forefront of an industrywide debate about the uses of AI in moviemaking. But for him, it’s a conversation he’s eager to have.
