VANITY FAIR – On a rainy April afternoon, Emilia Clarke enters the bright, airy Egyptian galleries of the Metropolitan Museum of Art the way so many movie-lovers before her have: quoting Billy Crystal in When Harry Met Sally. Adopting the unsourceable accent Crystal uses opposite Meg Ryan in a famously improvised scene filmed in this very room, Clarke starts stuttering, “Pah-pah-paprikash.” Our amused if bewildered guide, too young to get the reference, adds the 1989 rom-com to her list of movie recommendations from Clarke, who has already gushed about the 2017 religious drama Novitiate. Chuckling over this unlikely double feature, Clarke assures her, “You have two incredible movies coming your way.”

One reference the guide does get: Game of Thrones, the HBO juggernaut which stars Clarke as its most unstoppable heroine, Daenerys Targaryen. In fact, the very tour we’re taking, put together by a company called Museum Hack, is based on the series, and offers a fan-friendly survey of the sometimes inscrutable displays of the Met. You don’t have to be an art historian (our guide is an aspiring actress) to understand what Greek fire, Damascus blades, heraldry, mutilated men, samurai kamon, the dragon-born St. Margaret of Antioch, and an early female pharaoh have to do with wildfire, Valyrian steel, house words, and Clarke’s world-famous alter ego.

And yet, despite her fame, Clarke has managed to spend a full half-hour in the museum sponging up our guide’s trivia without being spotted. For years, Clarke’s brown hair let her hide in plain sight, but she recently bleached it an icy Targaryen blond. So, why the invisibility? Maybe it’s her height. “We both have a thing about our stature not quite being what people expect,” says her co-star Kit Harington, who, at five feet eight, has six inches on Clarke. Maybe it’s her outfit—the gray overcoat, cream sweater, and jeans are a far cry from the cloaks and armor of Thrones. Or maybe it’s her bright, decidedly non-intimidating personality. “When I’m goofing around with my pals, I’m unrecognizable,” she says. Harington calls Clarke’s humor “naughty,” and it’s certainly true that her informal, expletive-laced banter is a far cry from Daenerys’s imperious tones. “Sometimes, if I’m in a really bad mood,” Clarke notes, “people are like, ‘Khaleesi!’ ”
