The long cobblestone walkway and grand arches of Paris’ Invalides museum make for a reasonably dramatic entrance. Jared Leto, Noomi Rapace, Jack Harlow, Paul Dano and Taeyang were among the many celebrities who made the walk on the Givenchy show Wednesday.

Leto is attending his favorite fashion week shows — he’s a Givenchy regular — before taking per week or so off. Then it’s back to work, first on the filming of the “Tron” remake after which on to Lollapalooza in August along with his band 30 Seconds to Mars.

“It’s a movie I loved as a child,” he said. “It’s beautiful to enter into that world. I mean, it’s a childhood fantasy for me. It’s gonna be a superb one.” He plays an engineer who’s sucked into the digital world he created. His film about Karl Lagerfeld remains to be within the works, he added.

Leto has attended the Givenchy show for several seasons. “It’s incredible all of the exertions that goes into this quarter-hour. It’s absolutely stunning.”

Dano, who just served jury duty on the Cannes Film Festival, arrived on the show minutes after the trailer for his next film, “Dumb Money,” dropped. He talked about how he prepared for the role of the YouTuber Keith Gill, aka “Roaring Kitty,” behind the trading frenzy of the Game Stop stock drive.

“It’s a real story so there was plenty of fact to look into and plenty of research to be done, but I feel my predominant attraction to the character was that guy’s spirit — ‘Roaring Kitty’ — an excellent beautiful, spirited guy who was making videos on YouTube. So I spent plenty of time meeting his virtual self,” he said.

“The Batman”‘s Riddler was asked what he would do if he ever got here into some “dumb money” himself. “I might hope that I might also do my part to be a superb Samaritan,” he said.

Chinese pop star Fan Chengcheng was being a little bit of a fanboy, asking Leto and Harlow to pose for pics with him. The guy front row attendees happily obliged.

As is common practice for Asian fan clubs to lift a star’s profile or have a good time their achievements, Fan’s fans sent a billboard truck to circle the venue before the show. “I did see it,” he said. “And I’m so thankful for my fans for doing every part for me. It’s nice to see it, and I like it.”

“It was unbelievable, he brought style for [the] gentleman and hip hop all together,” Fan added in regards to the show.

Tyga can be a fan of Givenchy’s creative director Matthew M. Williams, and was wearing head-to-toe Givenchy from past seasons. “It was definitely a special style than a number of the previous shows, but I just like the tailoring of the suits. It was more formal, and I like that. A bit of more classic,” he said. The rapper is working on recent music but won’t have any releases before the tip of the 12 months, he added.

Evan Mock has done away along with his pink hair this season, and said he only plans to attend the one show this week.

“He’s a master at what he does and he treats everyone with kindness, and that’s all that matters to me,” he said of Williams. The Hawaiian-born Mock has been working on his own line, Wahine, for the past 12 months. The primary release brought varsity jackets, graphic T-shirts and hoodies, but he envisions it moving beyond contemporary skate-inspired clothing.

“It’s every part. I just desired to make a brand that I could create anything I desired to, like a tea set or a toothpick. Anything. It might be clothing, it might be accessories, it might be something you utilize each day,” Mock said. The skateboarder pulls in inspiration on the shows, he said. “I’m around a bunch of fantastic artists and friends.”
