A nice article on Missing filming in Europe...
Judd, who plays Becca Winstone, an ex-CIA agent in search of her kidnapped son, savored the opportunity to soak up local culture in between takes. "When we shot in Istanbul, I'd lie on my back on these ancient stone floors that were laid in 420 AD while I pondered the inscrutable," she says. "We shot on the rooftop of the Suleiman Mosque — no tourist goes to the … rooftop! We'd be in the middle of a take and have to hold the roll for the call to prayer. It was fabulous."
For Judd, "Missing" rekindled the wanderlust she experienced in her 20s, when the actress spent every spring in Paris. "I think it's very cool that they wrote to the locations," she says. "In Dubrovnik, you've got this incredibly enchanting city made of marble, one of the great old capitals of Europe. Doing chase sequences through the narrow stone alleys and over the rooftops of this walled city was magnificent. The whole point was to film outdoors and capture the beauty of this setting."
Had "Missing" been renewed for a second season, Poirier had planned on a fresh influx of locations — in fact, he had hoped to "do a different continent every year," he says. And while that now won't come to pass, they'll always have Paris.
