Blake Gopnik picks the exhibitions to keep an eye on this fall. In addition to the Museum of Modern Art’s blockbuster retrospective on Willem de Kooning, opening Sept. 18, here are seven more art exhibitions to note on your calendar. Sept. 17. Zaha Hadid: Form in Motion, at the Philadelphia Museum of Art, takes a rare look at the design work of a figure much better known as an architect. Hadid herself created the immersive display for her objects. Through March 25. Sept. 25. A Warhol double-header in the nation’s capital: Warhol: Headlines at the National Gallery of Art through Jan. 2 and Andy Warhol: Shadows at the Smithsonian’s Hirshhorn Museum through Jan. 15. Warhol is probably the most important artist of the last 50 years, but these shows suggest that his famous soup cans and Marilyns may not matter as much as his more subtle works, such as those that riff on the news and on illegible details from everyday life. Oct. 1. Pacific Standard Time is a festival of postwar art in Los Angeles that, with help from $10 million of Getty Foundation grants, will be filling almost all the city’s art venues. Through April 2012. Nov. 4. Maurizio Cattelan: All will present the complete works of this Italian trickster at the Guggenheim Museum in New York. His statue of Pope John Paul II felled by a meteor should be there, as should some version of the piece where he duct-taped his dealer high up on a wall. Through Jan 22. Tim Brakemeier, DPA / LandovLeonardo da Vinci Nov. 9. Leonardo da Vinci: Painter at the Court of Milan, at the National Gallery in London, will be the most complete display of Leonardo paintings ever presented—which means there might even be a dozen of them on view. (His drawings, and works by his pupils, will round out the show.) Through Feb. 5. Nov. 18. HIDE/SEEK: Difference and Desire in American Portraiture, a show about gender identity that is touring to the Brooklyn Museum, caused a ruckus last year when the Smithsonian censored one of its works. In its New York incarnation, let’s hope the focus can turn back to the fascinating art it presents. Through Feb 12.
