Adaptations
On 5 January 1992, Dirk Gently, Richard MacDuff, Dirk's secretary, and the Electric Monk all appeared in the Douglas Adams episode of the British arts documentary series The South Bank Show. Michael Bywater played Dirk, while Paul Shearer played both Richard and the Monk. Several characters from The Hitchhiker's Guide to the Galaxy were also featured, played by the original television series actors.
The book has been adapted for stage performance as Dirk and in 2005, some fans of Douglas Adams produced an amateur radio series based on the first book. Their efforts began and were coordinated on the Douglas Adams Continuum website. Three episodes were completed. Apart from the radio broadcasts, Douglas Adams recorded both unabridged and abridged readings of the first novel for the audiobook market.
A publishing company has been seeking the rights to produce a graphic novel adaptation, though art has been removed for legal reasons.
