This is it. The Ponds are departing and there'll be no more Doctor until the Christmas special. In this farewell episode, New York's statues come to life (the freaky Weeping Angels are back), and with Rory in grave danger, the Doctor and Amy face a race against time to locate him. Luckily, an old friend has come up with a novel way to guide them. Alex Kingston returns as River Song, with guest star Mike McShane (Robin Hood: Prince of Thieves). The Doctor will return in the Christmas special.
