More article than interview but there are a couple of new bits in here from the cast (including Damien), and from creator Paul Marquess about the creation of Suspects

Behind the scenes: C5's unusual Suspects | Televisual

"The most notable innovation about Suspects, which was well received at a press screening last month, is how it is scripted. Each episode is tightly plotted. The actors are given a clear idea about the beginning, middle and end of each scene. But they are not given word-for-word dialogue. “It would be wrong to say it is not scripted,” says Marquess. “But it would be correct to say that we don’t write the dialogue.”

Fay Ripley, who plays the lead detective inspector, says each episode was shot fast: “We received a document the night before filming with some bullet points and a strong plot.” The cast would then improvise each scene based on this information. She adds: “We are reacting in real time in this show – thinking very much on our feet.” Damien Molony, who co-stars as a detective sergeant, explains: “There is a very structured storyline – this is where the scene starts, this is where the scene ends, the scene must contain this information. But then, what happens when we’re filming the scene is really up to the actors, the director and the cameraman, as the scene is being filmed, in the moment. That’s what will make it very exciting to watch, I think. It makes it very real.”

Marquess sums up the process, saying: “We allow the actors to play the character rather than the line.”"
