"The Almost People" ends on a cliffhanger which brings several plot threads of the series to a head. The two-part story was filmed from November 2010 to January 2011, mainly at Caerphilly Castle. The Gangers were achieved with the aid of prosthetics, as well as computer-generated imagery for their contortions. "The Almost People" also features a Flesh double of the Doctor, which marked Smith's first time in prosthetic make-up. The episode was watched by 6.72 million viewers in the UK and received mixed reviews from critics, many noting that the cliffhanger overshadowed the actual story of the episode.
