I’ve never heard of him either!

Writer Signs on for ‘Hitchhikers Guide’
HOLLYWOOD (Variety) – Screenwriter Karey Kirkpatrick has come onboard to co-adapt the screenplay of Douglas Adams’ “The Hitchhikers Guide to the Galaxy.”
Adams originally penned feature adaptation prior to his death last May and will have a posthumous producing credit on the picture. Jay Roach, director of the “Austin Powers” franchise, is attached to take the helm and will serve as a producer.
“Hitchhikers,” which has previously been adapted into a novel, radio series, TV series and videogame, centers on Arthur Dent, who after discovering the Earth is meant to be flattened by a hyperspace freeway bypass, is whisked away by an undercover alien who is researching the “Hitchhikers Guide.”
Kirkpatrick previously wrote “Chicken Run,” “The Road to El Dorado,” “James and the Giant Peach” and “Honey, We Shrunk Ourselves.”
