, May 17 -- winning director Steven Soderbergh has defended his decision to use artificial intelligence in his new documentary John Lennon: The Last Interview, saying he believes filmmakers should be fully transparent about how they use the technology.

The film, which premiered Saturday at the Cannes Film Festival, is built around a two-hour interview that John Lennon and Yoko Ono gave to a San Francisco radio crew on Dec. 8, 1980, the day Lennon was shot and killed in New York.

During the interview, the couple spoke openly about their relationship, love, creativity, life after The Beatles, raising their young son and songwriting. Soderbergh said he was deeply moved by their honesty and warmth.
