Running Time: 45 minutes
Setting: London, 2008. As far as Martha's family are concerned, this episode takes place the day after Martha left with the Doctor in Smith and Jones. Therefore, although it's been several days since Martha's seen her family for her, it's only been one day for her family, who last saw her at Leo's birthday party.
Filming: Filming for this episode took place in and around Cardiff. Scenes inside the Southwark Cathedral were shot inside Wells Cathedral. Interior shots of Professor Lazarus's science institute were filmed on location at Cardiff Museum, and also inside the Welsh Assembly's Senedd building, located at Cardiff Bay.
