“It’s like the Orient — it’s insane,” Francisco Costa marveled, watching a burnt-orange moon rise over the Mediterranean Sea.

The Calvin Klein Collection creative director was exploring the spectacular grounds of the Villa Camille Amélie on the outskirts of Cannes, where Calvin Klein Collection, Euphoria Calvin Klein and the Independent Filmmaker Project hosted a party on Thursday honoring Naomi Watts, Lupita Nyong’o, Julianne Moore and Rooney Mara.

While the night sky proved impossible to capture on Instagram, the grounds provided plenty of fodder for Costa, who snapped pictures of the villa’s nymphaeum, an indoor artificial grotto with a basin supplied by waterfalls.

Nyong’o, on her first visit to Cannes, posed for photographers in front of an outdoor pool strewn with flower petals. “It’s a magical place, I think — I mean, right near the water and the full moon right now. It’s been an amazing reconnection with the outdoors,” she said.

The Oscar winner declined to confirm reports that she has joined the cast of “The Jungle Book,” director Jon Favreau’s upcoming take on the Rudyard Kipling tale. “I plead the Fifth,” she said with a smile.

Mara, the face of Calvin Klein’s Downtown fragrance, was taking a brief break from rehearsals for “Pan,” a live-action adaptation of another children’s classic, which also stars Hugh Jackman and Garrett Hedlund. The actress, who plays Tiger Lily, was still exploring the part. “She’s a warrior, she’s a little bit of a bad ass,” she suggested.

As guests enjoyed a live performance by British singer Jessie Ware, party chatter turned to the taxi protests against private car services like Uber, which have caused chaos at Nice Airport. But mostly, guests were relieved the sun has been shining on Cannes after last year’s torrential rains.

“That was the craziest red carpet I’d ever been on in my entire life last year, with that pouring, pouring rain,” Moore recalled with a shudder.

The actress was in town for a press conference to promote “The Hunger Games: Mockingjay — Part 1” and for the premiere of “Maps to the Stars,” which is in competition for the Palme d’Or, the top prize at the Cannes Film Festival — though she confessed she has yet to see the finished product.

Watts planned to attend a preview of “St. Vincent de Van Nuys,” the story of a young boy’s unlikely friendship with a cantankerous war veteran, played by Bill Murray. “I loved working with Bill, I just loved it,” she enthused. “He’s an oddball, but he certainly was a joy for me to work with.”
