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)
The fourth series of "Spooks" began transmission on Monday 12 September 2005 on BBC One at 9 pm with the first of a two-part story. The next day (13 September) the second episode was shown. The following week "Spooks" assumed a 9 pm Thursday slot, a break from the Monday 9 pm slot the previous series had traditionally occupied. Once again, the series ran for ten episodes and averaged 6.05 million viewers, a notable increase on the previous series.
