During the recording of "The Unquiet Dead" on 20 October, several pick-up shots were recorded at Headlands School in Penarth. The main recording on the block concluded in Q2 on 22 October. To help with the convenience of locations, the scenes with the Doctor and Rose on present-day Earth were shot during the third production block on 9 November. Filming took place at Helmont House on Churchill Way, and on Queen Street. Some additional shots involving the air ducts were shot at Q2 on 26 November. The filming of screens with Cassandra proved to be difficult, with one crew member comparing it to pushing around a faulty shopping trolley. Zoë Wanamaker was unable to be present on the set during the filming of her scenes so a stand-in had to be used.
