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 (series 7)
The writers and producers got together to discuss what direction they would take for the seventh series. They wanted to repeat the same style for series six, which was to add a serial element to be carried throughout the duration of the series. They got together to think about what they would believe to be a big political story that would affect politics in the United Kingdom in within twelve to eighteen months after their initial meetings early in 2008. They settled on using Russia, which was facing a resurgence in power after the Cold War, which the producers felt, in subtle ways, would threaten the security of the west. Sometime through the writing process, the producers set up a story-arc, Sugarhorse, to be a threat throughout the series and have it resolved by the finale. The writers enjoyed making the Sugarhorse storyline because it was one of the instances that "really brings Harry to the edge" and causing him to doubt everything he has done or achieved. The writing team took several meetings together to discuss what it is and how it should work into the storyline. Christian Spurrier noted it was "kind of a headache" to figure out how to "weave it in" to the series and work out what parts would be used in which episodes. The producers wanted to use a scene relating to Sugarhorse as the finale scene of every episode it was featured in, as the producers believed it would provide a "right hook" to the audience. Adding the new storyline would allow the series to return to the world of spying, truth, and who the characters should trust.
