Spooks (series 3)
The third series of "Spooks" was produced by Kudos Film and Television for the BBC. Much of the production crew from the first two series returned. New crew members were brought in with the requirement that they were fans of the series and have ambition, so that they can understand "Spooks". Andrew Woodhead was the series producer, with Jane Featherstone, Simon Crawford Collins and Gareth Neame as executive producers. Collins, who was the producer for the first two series, had to step back to executive producer, as he was overcommitted producing Kudos crime series "Hustle". Woodhead replaced him as he was accustomed to the show, but also added more vitality to the show. Christopher Aird was the assistant producer. The third series included five writers. Howard Brenton wrote the first, second and eighth episodes. Rupert Walters wrote the third and ninth episodes. Ben Richards wrote the fourth, sixth and tenth episodes. Richards previously wrote the ninth episode of series two, and accepted the offer to return. His script in the second series was his first script for television; he found writing easier as time went by. Raymond Khoury wrote the seventh episode. Series creator David Wolstencroft wrote the fifth episode. Wolstencroft was poised to write the next episode, but found himself committed to other projects.
Spooks (series 10)
In August 2011, Kudos announced that the tenth series of "Spooks" would be the final series. Executive producer Jane Featherstone decided to end the series during its writing stage, stating "It's very tempting to keep going, and we have had ongoing conversations with our partners at the BBC about it, but the heart of the show has become those two characters [Harry and Ruth] and I feel they own it. We've followed the arc of their personal story and I think they've brought us to a natural end, which you will all see played out later this year." It was also intended to end the series "in its prime." Writers Brackley and Vincent noted "there was always a strong possibility of it being the end, so throughout the [writing] process we were looking for ways to infuse it with a sense of finality. We'd done a fair bit of writing before it was made definite by Kudos – but had plenty of time to plot a true conclusion. And crucially, by the time we began to write the final ep, we knew it would be the last." They also stated; "When Kudos asked for our opinion, we said we'd hate to see it cancelled on a cliffhanger – it just wouldn't be right, or fair on the fans. Call us suck-ups, but you have to really admire Kudos for having the confidence to kill off a very successful show – purely because it's the right thing creatively." Firth believed the series is getting to a point where the producers were starting to run out of story ideas, as virtually every type of antagonists have been featured in past episodes.
