French actress Lea Seydoux may miss the Cannes film festival after she tested positive for Covid-19, a spokeswoman for one of her movies told AFP.

The James Bond star is appearing in no less than four films at the world's biggest film festival, including Wes Anderson's star-studded The French Dispatch, which has already been heavily delayed by the pandemic.

Three are in the running for the Palme d'Or, the top prize at Cannes.

Seydoux, who had already been fully vaccinated, is asymptomatic, the spokeswoman added.
