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 1)
Each episode took approximately two months to edit, and editing usually began as the episodes were still being shot. The editors would work on two episodes simultaneously. Following the completion of the episodes, Muskett added the score for them. The episodes include split screen sequences. Although the sequences were presented in a similar vein to the American action series "24", the split screen idea did not come from the show itself; Nalluri thought of it independently after visiting a pub one night after filming wrapped up. The series also introduced the premise of not including any production credits. The producers agreed that adding credits would be a waste of time, and that the viewers would pay no attention to them. However, they also saw this as an opportunity; as "Spooks" is a spy show, Wolstencroft had the idea that it would be "cool" to have a show that was anonymous, and it would fit the spirit of the series.
