Behind the Scenes

 * Though they did not film any scenes involving actual actors, members of the Doctor Who production team visited the city in 2006 to shoot some of the location footage seen in Daleks in Manhattan and Evolution of the Daleks. In post-production, the team later altered to make the city look as it had in 1930 in post-production and made sure that the scenes matched the scenes shot back in Great Britain featuring the main actors and extras. The New York filming marked the first time in a decade, since Doctor Who, that any production of Doctor Who had taken place outside of the UK, and first filming ever done in the United States.
 * Russell T Davies considered having the city be destroyed in The Stolen Earth but decided against it. (The Writer's Tale)
