“It’s amazing people watching,” noted a male member of Alicia Vikander’s trio of friends, who stood in the packed center of Chateau Marmont’s magazine clip-covered penthouse — where W Magazine (with help from Audi and Dom Perignon) feted this year’s cinematic standouts at their annual Best Performances party on Thursday night.

Golden Globe nominee Kirsten Dunst, early to arrive, made some party rounds with Rodarte designer Laura Mulleavy. Dunst, who said she’s currently working on “Midnight Special” with director Jeff Nichols, told Variety how excited she was about her second-ever Globe nomination, for “Fargo.” (She was first nominated in 1995, for her supporting role in “Interview with the Vampire.”) “Peggy’s such a crazy character, so maybe that’s it!” she speculated, as to why viewers particularly responded to her performance. As her for her own favorites, she was quick to name “Straight Outta Compton” and “Hateful Eight” — and said how much she enjoyed “the last half” of the latter, especially.

As luck would have it, Dunst later had a chance to meet “Hateful Eight” director Quentin Tarantino, to whom a friend introduced her, outside on the penthouse patio. Tarantino, however, noted that it hadn’t been the first time. “You were with Jake Gyllenhaal, out at a concert, and you got my a–,” he loudly quipped, recalling how she’d grabbed him by mistake. “I felt good about it!” Tarantino joked. “I was bragging about it!”

Steps away, “Hateful Eight’s” Christoph Waltz chatted with co-star Jennifer Jason Leigh — who appeared in W’s coveted February issue, along with party guests Elizabeth Banks, Kristen Wiig, Mya Taylor, Maika Monroe, Paul Dano and Jacob Tremblay, and cover stars Vikander, Rooney Mara, Brie Larson, Saoirse Ronan and Cate Blanchett.

Blanchett immediately summoned attention when she first walked in, and caught up with Waltz in room’s center. Photographers rushed to capture the shot — after which, one came back over and leaned into her. “I really loved your film,” he gushed. Blanchett, who mingled with German photographer Peter Linderbergh, who shot the issue’s portfolios, headed towards the door just before 9 p.m. (“I’ve been here since the Q&A,” she noted to a disappointed male friend, on her way out.)

Swedish fashionista Vikander, however, long held court in the middle of the penthouse, where partygoers frequently stopped to bestow congrats (for her dual nominations, for “The Danish Girl” and “Ex Machina”). “I’m going back and doing a French film,” she told a male acquaintance; had a moment with a female friend, whom she emotionally hugged; and spent a lengthy period of time talking to Hungarian director Laszlo Nemes.

Anthony Mackie, with whom she also mingled, mentioned to guests that he was here in town for TCA (he plays Martin Luther King Jr. in HBO movie “All the Way”). Still, he couldn’t wait to get back to New Orleans to go fishing (for catch, like catfish), and said he’s happiest when among boats and barnacles.

Meanwhile, well-heeled party guests from the film and fashion worlds — including Taylor Lautner (who posed with Monroe), Aziz Ansari (who got perturbed, when he was accidentally splashed with a drink), Monique Lhuillier, Max Azria, Joanne FroggattMichelle Monaghan, Helen Mirren, Vivienne Westwood, Julie Delpy, Gerard Butler, Lily James, Gael Garcia Bernal and Jesse Metcalfe — enjoyed flowing Dom, generously-served hors d’oeuvres like risotto balls and tuna tartar, and a buffet of salmon, steak and ravioli. after arriving in all-new Audi 2017 Q7 vehicles to the affair hosted by Stefano TonchiLynn Hirschberg and André Balazs.

A low-key Wiig circulated around, stopping to converse with “The Big Short” director Adam McKay and to have a laugh with Larson — who caught up with Dano and “Mr Robot’s” Rami Malek. Malek, nominated for his first Globe, came to the party on the later end with some childhood friends, and was overheard teaching party guests how to pronounce the phrase for an Egyptian toast. “It’s Fee Saḥitkum,” said the Egypt-born star. “It’s a really nice wish.”
