The Academy Museum of Motion Pictures keeps on partying.

Just four nights after a gala opening celebration was held at the new complex located on the LACMA campus in Los Angeles, Robert Pattinson and H.E.R. co-chaired, along with museum director and president Bill Kramer and Vanity Fair editor Britt Hennemuth, the Premiere party on Wednesday night. The guest list included Rebel Wilson, Zooey Deschanel, Clea DuVall and more.

“It’s strange that it doesn’t exist already in L.A.,” Pattinson told Variety of the long-in-the-works museum. “It’s bizarre. So I’m very very honored to be a part of it.”

As a film buff and a newly minted Academy member, the “Batman” actor was particularly eager to take in the Hayao Miyazaki exhibit and the 1,000 seat David Geffen theater. “Being really geeky about it, the technical specs sound insane,” he added.

One piece of Academy history that’s not in the museum, though, is H.E.R.’s Oscar statuette, which is still on her kitchen table.

“I’m working on getting a really good shelving situation,” she explained. “So as soon as that happens, it’s going to be shining bright under a light in my house.”

The museum, which includes multiple exhibit spaces, a gift shop, Fanny’s restaurant and café and the David Geffen Theater, opens to the public today Sept. 30, after a morning dedication ceremony and ribbon-cutting. Among those set to deliver remarks today are Kramer, Tongva leaders Jimi Castillo and Virginia Carmelo, the Academy’s Dawn Hudson and David Rubin, Mayor Eric Garcetti, producer Effie T. Brown, California Film Commission executive director Colleen Bell, county supervisor Sheila Kuehl, city council member Nithya Raman and Netflix boss Ted Sarandos.

The museum is quickly becoming the hottest event space in the city. WIF will hold its annual awards gala there next week followed by the premieres of “House of Gucci,” Ridley Scott’s drama starring Lady Gaga, and Guillermo del Toro’s “Nightmare Alley.”
