The use of artificial intelligence could become a ferocious battleground during movie awards season, as at least two major contenders were revealed to have used voice-cloning to enhance actors' performances. In an interview with moving-image tech publication Red Shark News, The Brutalist editor Dávid Jancsó said that, in an effort to create Hungarian dialogue so perfect "that not even locals will spot any difference", Jancsó fed lead actors Adrien Brody and Felicity Jones's voices into AI software, as well as his own. In the film, Brody plays Jewish-Hungarian architect László Tóth, who emigrates to the US after the second world war, and Jones is his wife Erzsébet. Jancsó, a Hungarian speaker, said that while Brody's mother was an émigré from Hungary in real life, "coaching" and re-recording via ADR (automated dialogue replacement) with both the original actors and stand-ins "just didn't work". Jancsó said he then employed an AI tool developed by Respeecher, a Ukraine-based company who were previously involved in the "cloning" of the voice of James Earl Jones for the TV series Obi-Wan Kenobi, to add individual sounds and letters to both Brody and Jones's Hungarian-language dialogue.
