Chronologically, this was the last televised live-action story to feature Matt Smith dressed in the Eleventh Doctor's brown tweed jacket. He would appear in his purple cashmere jacket for the remainder of his tenure.
Although the Central Park recording had attracted considerable attention, the production team was flabbergasted to discover more than one thousand fans waiting for them at Tudor City, a crowd which, fortunately, turned out to be largely cooperative.
This story features the last appearance of the title sequence that debuted in The Eleventh Hour (2010). Beginning with The Snowmen (2012), a new title sequence was used, and overall this is the last revived series title sequence to feature only the time vortex - a concept which had been used since 2005.
A significant trim in post-production involved the Doctor and Amy reflecting on how much time was passing between the Time Lord's visits. Steven Moffat had now come to feel that the sentiment was more elegantly conveyed in The Power of Three (2012), and therefore needed less emphasis.
Originally, the Daleks were the focus on Amy and Rory's departure. Steven Moffat decided that the Weeping Angels fit the story better and Asylum of the Daleks (2012) became the season premier.
