CANNES, France—French authorities believe arson may have played a role in a power outage Saturday in southeast France that threatened to jeopardize the Cannes Film Festival’s closing celebrations, including the much-anticipated Palme d’Or ceremony.
Power was restored hours before the ceremony, around 3 p.m. local time, as music began blasting again from beachfront speakers. The end of the blackout was greeted with loud cheers from locals.
