The Toronto International Film Festival (TIFF) has kicked off with notable appearances from celebrities like Jennifer Lopez, Pamela Anderson, and Elton John, who are promoting their latest films. Highlights include Ben Stiller's dramedy 'Nutcrackers' and Demi Moore and Margaret Qualley in 'The Substance,' directed by Coralie Fargeat. Despite some initial glitches and a brief protest against major sponsor RBC, the festival has drawn significant crowds. This year's lineup features a mix of Hollywood blockbusters and international films, with standout titles like 'Heretic' starring Hugh Grant and 'Hard Truths' by Mike Leigh. The festival, which runs until September 15, is expected to set the stage for several potential award-winning films.
