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.
The Professionals (TV series)
After the series ended, ITV produced "Dempsey and Makepeace" as its replacement, while Raymond Menmuir produced "Special Squad" for Australia's Network Ten in the mid-1980s, following "The Professionals"' format. A revival series, "" was produced for Sky in the late 1990s and starred Edward Woodward, but it was not a success. The BBC introduced "Spender" in the early 1990s, which featured several "Professionals" influenced themes. The BBC television series Spooks that was broadcast in 2002 also had a fact action style inspired by The Professionals.
