Los Angeles: 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." 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. But Tilly Norwood - a winsome figure with shoulder-length brown hair, brown eyes, a British accent and her own social media profile - was the star. "To be clear, 'Tilly Norwood' is not an actor," the union said in its statement. Not everyone is convinced Tilly Norwood packs such potential.
