The Angels Take Manhattan [SEP] Introduction
Amy and the Doctor attempt to rescue Rory, but the Doctor realises along the way that this adventure will be his last with Amy and Rory. Actors Gillan and Darvill both departed the series during this episode. Amy's departure from the series was a compromise between Gillan and Moffat. Moffat wrote several endings and situations for the couple, eventually deciding to incorporate the Weeping Angels. Despite being Amy and Rory's last episode, it was not the last episode Gillan and Darvill filmed. Production took place in April 2012, with location filming in Wales and a small crew filming in the United States in Central Park.
