Has Spain just come up with its own Downton Abbey? The Time In Between, a co-production from Antena 3 and Boomerang TV, debuted in Spanish primetime on Monday night, winning its slot and becoming the best local drama premiere of the last eight years with a peak of 5.7 million viewers and an overall 25.5% share. (Check out the subtitled trailer below.) The miniseries was up against The Voice and popular series Isabel, so its success is no small feat, and critical reaction has been glowing. The 11-part mini is based on El Tiempo Entre Costuras, the bestseller by María Dueñas which has sold over 3 million copies. It stars Adriana Ugarte, Raúl Arévalo (I’m So Excited) and Hannah New of Starz’s upcoming Black Sails. Set during the Spanish Civil War and the run-up to World War II, it’s the story of a woman raised by a poor single mother and taught to be a seamstress. When she falls for a handsome young man, she moves with him to Morocco and spends months living the high life. But when the money runs out and she falls pregnant, he leaves. She ultimately builds a new life and becomes the most sought-after couture designer for the socialite wives of German Nazi officers. She also begins working for the British government, passing information to the Secret Service. The series has high production values and looks sharp. Boomerang’s Ruth Martinez tells me it was “shot like a feature” and is one of the most ambitious TV productions of recent years. She has had interest and offers from several European territories, although buyers did not see the first full episode until just before its airing on Monday (it skipped the recent Mipcom TV market in Cannes). As for a U.S. sale, given the numbers it picked up in Spain, the book’s popularity and the current taste for period dramas, an adaptation certainly seems a possibility. Here’s the trailer, judge for yourselves:
