Johnny Depp, Catherine Deneuve and Ruben Östlund among those to open the Cannes Film Festival. Chiara Mastroianni, the mistress of ceremonies, has insisted on the "emotion" of the festival.

The festival seems to feel guilty for being a place of celebration, writes David Bianculli. "We gladly glossed over the supposedly capricious attitude Johnny Depp on the set of the film, which opens the festival," he writes. "The team is, in any case, all to its "emotional" to present this feature film which takes place in Versailles," he adds.
