ANTIBES, France (AP) — Some of the biggest stars in the French Rivera for the Cannes Film Festival made appearances at the 30th annual amfAR gala to raise money for AIDS research. Demi Moore, whose film “The Substance” was caused a stir at Cannes, hosted this year's gala, a role launched by Elizabeth Taylor in 1993. The red carpet at the exclusive Hôtel du Cap, Eden Roc, was awash with models, actors, singers and fashion designers as well as plenty of festival movers and shakers, who paid thousands of euros for a table at the hottest event in town.
