Stephen Mangan is to bring to life late writer Douglas Adams' detective Dirk Gently for the first time on screen in a new BBC adaptation.
Stephen, best known for his role in Green Wing, will star in the BBC Four film alongside Helen Baxendale.
Much-loved author Adams, who created The Hitchhiker's Guide To The Galaxy, first wrote about the anti-hero in his cult novel Dirk Gently's Holistic Detective Agency in 1987.
Stephen said: "I've been a fan of Douglas Adams ever since the Hitchhiker's radio series which I used to record as a child and listen to over and over again in my bedroom. It's such a thrill to now be playing one of his brilliant characters.
"Dirk is a chaotic, anarchic force of nature with a totally unique take on the world. He is described as 'lazy, untidy, dismissive and unreliable'. I've absolutely no idea why they thought I'd be right for the role."
Ed Victor, Adams's agent, said: "For all the years I represented the late, great Douglas Adams, the most substantial frustration for both of us was that we couldn't get films made either of Hitchhiker or Dirk.
"Douglas once said, memorably, that 'getting a film made in Hollywood was like trying to cook a steak by having a bunch of people come into the room and breathe on it'.
"Well, we did eventually get a film made in Hollywood of Hitchhiker and, tragically, Douglas didn't live to see it. Nor will he see this adaptation of Dirk - but it's worth bearing in mind that Douglas always thought Dirk would make a better film than Hitchhiker."
