FREEZE FRAME: Robert Pattinson wears his sunglasses at night — along with a sleek tuxedo and biker jacket — in the spring campaign for Dior Homme, which breaks Saturday in magazines including Citizen K Homme Sport in France, Esquire Big Black Book in the Middle East, GQ in China and Style Magazine in Italy.

Karl Lagerfeld shot the ads in a film-noir style right outside his Left Bank photo studio.

“I love to take photos at night in the streets,” Lagerfeld said. “That is my outdoor studio.”

The designer and photographer is a particular fan of a tiny street that runs between the Rue de Lille and the Rue de Verneuil. “Nobody comes or goes there,” he said.

As for Pattinson, “he is very easygoing and easy to photograph. But at the same time there is something mysterious about him, which I love,” Lagerfeld said. “His profile is the modern version of an antique coin.”

Pattinson was in thrall of the outdoor set.

“I’m always floored at the undeniable beauty of Paris. And at night in the alleys and the side streets, emptied of crowds, it’s almost more breathtaking,” he told WWD. “Contrasting shadows make everywhere you look seem like a frame from a movie.”

In the throes of an expansion drive under Serge Brunschwig, the number-two executive at the French fashion house, Dior Homme runs multiple campaigns customized for various media channels. Fall spots feature personalities including rapper A$AP Rocky and filmmaker Larry Clark.

Kris Van Assche, creative director of Dior Homme, said Pattinson embodies “a rebellious contemporary icon” and is part of “the exploration of the diversity of the Dior Homme man.”
