LOS ANGELES (Reuters) -The recent debut of an AI-generated “actress” dubbed Tilly Norwood, and its producer’s boasts of interest from studio executives, sparked a backlash on Tuesday from the SAG-AFTRA actors union, condemning the replacement of human performers with “synthetics.” The Hollywood buzz around Tilly Norwood, introduced on Saturday at a film industry conference in Zurich, and the union’s scathing reaction to it reflected the dread many in the creative community feel about the intersection of artificial intelligence and show business. Dutch actor-producer Eline Van der Velden, whose London-based AI production studio Particle6 created Tilly Norwood, said during her presentation at the Zurich Summit the project was starting to turn heads.
