DON’T PANIC!
These are the words emblazoned on front cover of The Hitchhiker's Guide to the Galaxy, a repository of knowledge on how to make your way through the universe for less than thirty Altairian Dollars a day. Provided you don’t stop at too many bars along the way.
The series covered the Primary Phase of the radio play, with the script remaining largely unchanged. The series’ primary source of humour was found in both the reactions of Arthur Dent to the wider galaxy and the Guide’s explanations of various pieces of trivia (narrated in the soothing vocals of Peter Jones).
The series was rather impressive with special effects. Of particular note is Zaphod’s second head, a full-sized, mechanical monstrosity that would break down during filming and loll around next to Mark Wing-Davey’s real head. It was rumoured at one time that the cost of repairing it outstripped some of the actors' salaries. The CGI effects have not dated particularly well, though for the time of making the series (1981), they were considered to be high quality. The graphical layouts that accompany the Guide’s explanations are also fairly rudimentary by modern standards, but help to convey the charm and tone of the series.
The H2G2 franchise has generated enough popularity to see a Trilogy of Five books written by Douglas Adams, (plus a sixth by Eoin Colfer), a text adventure video game and a film starring Martin Freeman as Arthur Dent. Whilst the film itself has received generally middling reviews, the books have seen widespread popularity.
H2G2 is one of those concepts that endures. The TV series can be found quite cheaply, and the radio plays, film and books still command a strong following, with even a National Towel Day on the 25th of May to celebrate one’s love for the series.
