简介：<p>　　Green Wing and Free Agents star Stephen Mangan is to play the lead role in BBC4&#39;s adaptation of the late Douglas Adams Dirk Gently&#39;s Holistic Detective Agency.<br/>　　Mangan will be joined by Darren Boyd as his sidekick Richard MacDuff and Cold Feet and Friends actor Helen Baxendale, as MacDuff&#39;s girlfriend Susan.<br/>　　Adapted by the Bafta-winning writer Howard Overman – who is also behind Misfits, Vexed and Merlin – Dirk Gently&#39;s Holistic Detective Agency follows the exploits of Adams&#39;s chaotic character as he uses his unusual methods to solve crimes.<br/>　　Mangan said: &quot;I&#39;ve been a fan of Douglas Adams ever since the Hitchhiker&#39;s radio series which I used to record as a child and listen to over and over again in my bedroom. It&#39;s such a thrill to now be playing one of his brilliant characters.<br/>　　&quot;Dirk is a chaotic, anarchic force of nature with a totally unique take on the world. He is described as &#39;lazy, untidy, dismissive and unreliable&#39;. I&#39;ve absolutely no idea why they thought I&#39;d be right for the role.&quot;<br/>　　The Dirk Gently books have formed the basis of a play and a BBC Radio 4 series but have never before been filmed for TV.<br/>　　Adams&#39;s agent, Ed Victor, said: &quot;For all the years I represented the late, great Douglas Adams, the most substantial frustration for both of us was that we couldn&#39;t get films made either of Hitchhiker or Dirk.<br/>　　&quot;Douglas once said, memorably, that &#39;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&#39;. Well, we did eventually get a film made in Hollywood of Hitchhiker and, tragically, Douglas didn&#39;t live to see it. Nor will he see this adaptation of Dirk – but it&#39;s worth bearing in mind that Douglas always thought Dirk would make a better film than Hitchhiker and I feel sure that this new TV drama with a terrific script by Howard Overman will prove his point.&quot;<br/>　　Shooting begins this week in Bristol on the 60-minute drama, which is being made by ITV Studios in association with the Welded Tandem Picture Company.<br/>　　The Dirk Gently production is to be directed by Damon Thomas – who also directed BBC4 drama The First Men in the Moon – and will air early next year.</p>…
