Two days before the start of the much delayed, and anticipated, Cannes Film Festival, the town awoke to a rainy, muggy Sunday with little action on the ground. And while the skies cleared later in the day, it remained difficult to discern the festival vibe. Apart from at the Palais proper, there’s no sign of the promotions we’re used to seeing here. That goes for posters adorning hotels or piers for any film, regardless of provenance.
