the Cardiff Council issued a press release naming the streets where they would be filming. Studio filming principally took place in August and September in the Newport warehouse Unit Q2. The lift movement was recorded at Broadcasting House, Cardiff on 11 September. Special effects producer Mike Tucker was reminded of the James Bond film The Man with the Golden Gun when reading the scene in which the Nestene's lair is blown up, and sought to display it as a major effect. The production team built a one-sixth scale model of the paper mill where the explosions were filmed. Tucker did a model explosion for the destruction of Henrik's as well, although that was only for the roof; the rest was done by CGI.

This change was eventually embraced by the executive producers. Davies remarked that he originally wanted to take Rose and the audience inside the TARDIS in all one shot, but this was not feasible with the budget. This effect would later be accomplished in the 2012 Christmas special, "The Snowmen".

The leaked episode did not contain the new arrangement of the theme tune by Murray Gold. The leak was ultimately traced to a third party company in Canada which had a legitimate preview copy. The employee responsible was fired by the company and the BBC considered further legal action.
