Behind the scenes
At the time that Sophie Aldred got the part of Ace, she was back chorus on Fiddler of the Roof.
As she stepped out of the phonebooth after getting the news from her agent, John Scott Martin, who's been on Doctor Who and was playing a Rabbi alongside her, handed Sophie a postcard with three Daleks, which read, "Welcome to the family. You will not be exterminated." As she later recounted the story, she asked how he knew, and he said he just felt she was right for the part.
