If a trip to the Vatican doesn’t fit your busy schedule, consider an alternative pilgrimage to the Academy Museum of Motion Pictures, in Los Angeles, to gaze upon the sacred-profane relics collected in tribute to “John Waters: Pope of Trash.” At the age of 77, an enfant terrible turned avuncular dandy, Waters has made his Renaissance mark as an author, raconteur, advice columnist, and Baltimore’s droll ambassador-at-large, but he remains most notorious as the director of Pink Flamingos, Mondo Trasho, Polyester, Hairspray, and other polymorphous burlesques. This exhibition, 400 items strong, lays out a buffet of campy memorabilia (the roach dress from Hairspray, the scratch-and-sniff Odorama cards for Polyester), and goes big with retrospective screenings of Waters’s oeuvre, including rare showings of Hag in a Black Leather Jacket, made when he was 17, and the early, silent Eat Your Makeup. As if all this weren’t festive enough, the Academy Museum is also unveiling an augmented-reality interactive playland that will enable visitors to “transform themselves into some of Waters’s most iconic characters, including Tracy Turnblad in Hairspray and Divine in Pink Flamingos.” It’s like Barbie’s Dream House for the truly, madly wiggy. —James Wolcott
