Sam Black (Gabrielle Anwar) replaced Julie as the head of the graphics team in the second series. Sam is very fashion conscious and a flirt, and is surprised when an actor rejects her advances in favour of Sarah. Anwar had auditioned for the role of Lynda. (Many actors who unsuccessfully auditioned for main characters were invited back later for guest roles.) Moffat had expanded the role of Julie after the first series, but Lucy Benjamin was unavailable for series two. Sam, therefore, was basically the character of Julie under a different name, especially in her earlier episodes.
