Producer James Goss said: "Ten years after we started, the Torchwood monthly range is coming to an end. John Ainsworth's first conversation with me when he joined as Senior Producer was 'you’ve got to keep it going to 100', and so we have.

"We took Ianto to space, Suzie to the bottom of the sea, Captain Jack moved to suburbia, and Rhys and Gwen fought monsters without getting out of their car. Somehow, over those ten years of disasters and BAFTAs, the cast have done their best to find time for us, and we've loved working with them all.

"It’s been the longest job I’ve ever had and the one I’m quietly proudest of. So many stellar writers have done their first Big Finish work at Torchwood - Tim Foley, Juno Dawson, Lauren Mooney and Stewart Pringle - and it's been the privilege of my life to do so much of it with Scott Handcock, supported by Lisa Bowerman, Bethany Weimers and David O'Mahony.

"It’s also all been scored by Blair Mowat, a man simply too famous and busy to do it anymore. But he's scored every single monthly range adventure and it's been remarkable. We've found diverse and interesting stories, we've broken hearts, and provided inspiration for pet names and tattoos. What greater achievement is there? Big Finish is for the love of stories and has let us tell 100 great ones."

Lead actor Tom Price, who reprises the role he originally played in the Torchwood TV series, said: "Andy gets to do some ace detective work and finds himself quite scared. He's often found himself in scary situations, but this is more psychological. It's one of those scripts that really can make their hairs on the back of your neck stand up."

Writer Lauren Mooney added: "The Flawless Man is more like a police procedural than anything we’ve written before. We were quite inspired by The X-Files! Over the course of this investigation, Andy becomes obsessed with an unfinished student film and gets caught up in the seeming delusions of the boys who made it that the monster from the film had become real."

And, the episode’s other writer Stewart Pringle said: "One of the big inspirations for this story was the idea of these projects that bind you together when you're younger and then sit gathering dust somewhere. What if some of the horrors from that period became real and found their way into your adult life?

"The initial jump-off for this was the idea of doing found footage at Torchwood, in the realms of Blair Witch and Cannibal Holocaust, and also thinking of Ring and the idea of a film that comes to possess you, and that idea of a curse existing in an object, like M R James' Casting the Runes. There's a whole big potpourri of horror stuff in there!"
