Behind the scenes[]

Announced on 26 January 2007, BBC Radio 4 commissioned Above the Title Productions to make eighteen 30-minute adaptations of Douglas Adams' Dirk Gently books (including The Long Dark Tea-Time of the Soul and the unfinished The Salmon of Doubt), running in three series of six episodes.

The first series began on 3 October 2007 and features Harry Enfield as Dirk, Billy Boyd as Richard, Olivia Colman as Janice, Jim Carter as Gilks, Andrew Sachs as Reg, Felicity Montagu as Susan, Robert Duncan as Gordon, Toby Longworth as the Monk, Michael Fenton Stevens as Michael, Andrew Secombe, Jon Glover, Jeffrey Holland, Wayne Forester and Tamsin Heatley.

The script for Dirk Gently's Holistic Detective Agency was written by Dirk Maggs, who also directs, and John Langdon. The show was produced by Maggs and Jo Wheeler. As with the previous Hitchhiker's series, the CD version features greatly expanded episodes. There are a number of structural and detail differences between the radio adaptation and the book, mostly to aid the comprehension of the story when split into six half-hour episodes.

The BBC radio adaptation of The Long Dark Tea-Time of the Soul, starring Harry Enfield, Peter Davison, John Fortune and Stephen Moore was broadcast on October 2008.

A third series was planned, based on Douglas Adams' unfinished draft of The Salmon of Doubt that would've been adapted and completed by Kim Fuller, however these plans were scrapped and the series remained undeveloped; reasons for this include the development of the BBC Four television series and Dirk Maggs parting ways with Above The Title Productions to form his own company, Perfectly Normal Productions.
