A power cup in the south-east of France temporarily disrupted the projections on the last day of the Cannes Film Festival.
About 160,000 houses in the city of Cannes and the surrounding municipalities lost electricity on Saturday, said the French electricity operator RTE.
Police investigate a possible criminal fire attack as the main cause of the incident.
The organizers of the International Film Festival say that the closing ceremony will take place as planned because they have an alternative power supply.
The drop in power assigned 160,000 houses in the Alpes-Maritimes region. The supply was restored at 3:00 p.m. local time (11:00 GMT), according to RTE.
In Cannes, shops and restaurants had trouble working during the Cup.
“Another hour and I will throw everything,” said Laurent Aboukrat, who owns the restaurant Jamin de Canne, at the AFP press agency. He said his fridges had left since morning
“Cannes is in a total slowdown, the collapse, there is no coffee anywhere, and I think that the city is short of croissants, so it’s like a crisis territory,” Australian producer Darren Vukasinovic told Reuters.
Police are investigating a possible criminal fire attack on an electricity substation. “We are examining the probability that a fire begins deliberately,” a spokesman for the gendarmerie told Reuters.
Saturday is the last day of the Cannes Film Festival. French actress Juliette Binoche and her jury should announce the winner of the Palme d’Or – the highest prize awarded to the festival.
Several projections were interrupted by the morning cup, before the organizers could move to private generators.
