would have felt badly let down, because you can never portray that world on the screen as well as it's been done in people's own imaginations...If you just do a straight adaptation like The Hitchhiker's Guide film, people are always going to be quite brutal about it because it's never going to live up to their expectations." Stephen Mangan, writing a BBC blog on the programme stated "In my opinion, Dirk Gently's Holistic Detective Agency and The Long Dark Tea-Time of the Soul are unfilmable as written...too much happens, there are too many ideas". The pilot concentrates on two relatively minor plot strands in Dirk Gently's Holistic Detective Agency: the disappearance of a cat, and the simultaneous disappearance of billionaire Gordon Way. Although time travel is involved in the solution, the novel's entire St Cedd's College / Electric Monk / Coleridge strand is omitted, although key words relating to these elements do appear on Dirk's whiteboard when it is first seen, though they are never subsequently referred to. Other elements from the book, such as the trapped sofa, are also absent and the setting is updated to 2010, with email and voicemail replacing the answering machine messages in the book. There are changes to the characters too, one notable one being that Susan is Gordon's ex-girlfriend rather than his sister. Several additional elements from Adams' novels, in particular St Cedd's College, were later to appear in the full series. Interviewed about the series, Mangan noted that "All three episodes are very different in tone and you get a different Dirk with each one...He's on the run from the police in one of them and in another there's a bit of romance in the air, which for Dirk is a surprise because he's probably the most asexual character on TV... There seems to be a vogue for dark, realistic, gritty detective series, apart from perhaps Sherlock. Dirk has so much humour in it. How many other detectives mix detection with quantum mechanics or drive a 30-year-old brown Austin Leyland Princess?" Each episode of series one was written by different writers, who are mostly known for their contributions to science fiction and fantasy programmes; series creator Howard Overman also created Misfits and has written for Merlin, Matt Jones has previously written the Doctor Who stories "The Impossible Planet"/"The Satan Pit" and Jamie Mathieson wrote the film Frequently Asked Questions About Time Travel
