Spooks (series 1)
Kudos Film and Television developed "Spooks" after releasing Channel 4 medical drama "Psychos" in 1999, though the company initially faced friction from television networks which saw no potential in a post-Cold War spy show. The producers later successfully pitched the series to the BBC after the networks' commissioning teams were replaced. Four episodes were being written when the September 11 attacks took place, and the some scenes were rewritten to take the event into account to show the audience "Spooks's" goal of fighting terrorism. Throughout production, the producers were advised by former intelligence officers from the Security Service, KGB and Central Intelligence Agency. Filming took place from November 2001 to March 2002.
Spooks (TV series)
In episode seven, Fiona Carter leaves because the actress portraying her, Olga Sosnovska, was pregnant during filming and chose to leave the programme. In that story arc, Fiona attempts to kill her deranged ex-husband, whom she thought was hanged several years earlier. However, her ex-husband ultimately abducts her and later shoots her dead in Adam's presence during her attempted escape. Her character is replaced by Jo Portman (played by Miranda Raison), a new arrival at MI5 who was recruited by Adam in a previous episode.
