Cast member of Palme d’Or contender shot in Kent says the high number of chaperones and intimacy coordinators on set was over the top

Is Britain leading the way in protecting young people and children from the potential traumas of working on a film set, or has it all gone far too far? Two of the most prominent European stars attending the Cannes film festival, both with high-profile premieres, have very different views.

Franz Rogowski, the acclaimed German actor who plays a key role in Bird, British director Andrea Arnold’s contender for the top Palme d’Or prize, said this weekend that the proliferation of chaperones and intimacy coordinators that had been required on the shoot on location in Kent qualified as well-intended “madness”.

The weather didn’t play ball, but Magnus von Horn’s fierce fairytale and Andrea Arnold’s kitchen-sink take on English mysticism should count among the first-week highlights for Greta Gerwig’s jury

The Cannes film festival opens just as the heavens do, too. It’s raining on the red carpet and on the black limousines and on the immaculate white pavilions that line up on the beach. The rain falls on the A-listers as they climb the stairs to the Palais, and on the stoic huddled masses who gather behind the police cordons. Everybody’s bedraggled and windswept; it feels as though the whole town’s been at sea. “My main wish is that we see some great films this year,” says Iris Knobloch, the festival’s president, casting an anxious eye at the sky. “But also I’m wishing for a little sunshine as well.”

If it’s raining in Cannes, it means there’s a glitch in the script. It’s one of the event’s in-built paradoxes that a festival which predominantly plays out in darkened rooms should be so dependent on good weather; so in thrall to its complementary circus of photocalls, yacht parties and open-air film screenings. All it takes is a downpour to trigger a disturbance in the force, a creeping sense of existential dread. The punters came expecting Technicolor. But the scene is all wrong: the world has gone monochrome.
