French actress Lea Seydoux may miss the Cannes festival after testing positive for Covid-19. The character star – who is double-vaccinated and asymptomatic – is appearing in four films at the world’s most famous movie festival. The event is being held in person on the French Riviera, with organizers insisting they need strict measures to avoid infections. Even so, rumors of a possible “Cannes cluster” are circulating. These are strongly denied by festival director Thierry Fremaux. “Yesterday we did quite 3,000 tests (on festival-goers) and that we don’t have any positive cases,” he said on Saturday. “We are having to mention this to indicate that the rumors of a Cannes cluster are unfounded.” Ms. Seydoux, 36, had yet to reach the festival when she discovered she had tested positive. Representatives for the actress said she is going to only travel if given the okay by doctors. All four of her films are being shown next week. First up is director Wes Anderson’s star-studded The French Dispatch, which has already been heavily delayed by the pandemic but will have its public presentation on Monday. This is followed by Arnaud Desplechin’s Deception on Tuesday, Ildiko Enyedi’s The Story of My Wife on Wednesday, and Bruno Dumont’s France on Thursday. Three of the titles are within the running for the Palme d’Or, the highest prize at Cannes. Seydoux previously won the prize in 2013 for her performance in Blue is that the Warmest Colour.
