Marion Cotillard on AI actors: 'for now they act like potatoes'
Marion Cotillard told a San Sebastián press conference that AI actors still act like potatoes, but she named no specific AI film or performer, and her longer answer on spotting AI survives only in Spanish reports.
Marion Cotillard was at San Sebastián on 24 September to promote Nicole Garcia's Milo, a human drama, when someone asked her about AI actors. The Oscar winner answered laughing: "I think I would be very afraid the day I was moved by an AI actor. For now, I find that they act like potatoes, and that reassures me." Acting like a potato is everyday French for stiff, wooden acting.
The wire stopped at the joke, but Spanish outlets in the room carried a longer answer. According to Europa Press, she said she always tries to detect AI, which is still detectable today, and teaches her children to detect it too. She also said AI can be formidable in many trades and only becomes disconcerting when it touches art.
That detection habit is the useful part for anyone building a synthetic performance. The usual debate runs on pixels, and she is describing a viewer who sits down already hunting for the moment the performance breaks. In practice, a generated character needs a specific want, a history and a reason to be on screen, and work that says what it is up front leaves that viewer nothing to catch.
She did not name any AI film or performer, including Tilly Norwood, in any account we read.
