Running parallel to the festival's main competition, Un Certain Regard, French for "of a certain regard," offers the chance for young directors to feature in the prestigious cinema showcase.

The festival top prize, the Palme d'Or, will be announced at the closing ceremony on Saturday.

This year's event, the festival's 74th edition, has been pared back from its usual hectic 12 days of glitzy movie premieres, with fewer attendees and less parties.

However the red carpet has brimmed with film stars including Matt Damon, Sharon Stone, Jessica Chastain, Tilda Swinton and Sean Penn in a show of support for cinema, an industry crushed by the COVID-19 pandemic.
