He’s faced Daleks, Cybermen and the Silence, but this season The Doctor will face one of his greatest challenges – saying goodbye to Amy and Rory. The eleventh Doctor, Matt Smith, described the five-episode arc beginning this Saturday as “the fall of the Ponds.” We caught up with Smith at BBC America’s offices before the premiere of “Asylum of the Daleks” at Ziegfeld Theater in New York City to talk about the new season, his love of New York City and his secret desire to see The Doctor swinging from trees with Tarzan.
