of the novel with a "movie tie-in" cover, and collectible prints from the film, packaged in a replica of the film's version of the Hitchhiker's Guide prop. A single-disc widescreen or full-screen edition (Region 1, NTSC) were made available in the United States and Canada on 13 September 2005.

Stage shows There have been multiple professional and amateur stage adaptations of The Hitchhiker's Guide to the Galaxy. Three early professional productions were staged in 1979 and 1980. The first of these was performed at the Institute of Contemporary Arts in London, between 1 and 19 May 1979, starring Chris Langham as Arthur Dent (Langham later returned to Hitchhiker's as Prak in the final episode of 2004's Tertiary Phase) and Richard Hope as Ford Prefect. This show was adapted from the first series' scripts and was directed by Ken Campbell, who went on to perform a character in the final episode of the second radio series. The show ran 90 minutes, but had an audience limited to eighty people per night. Actors performed on a variety of ledges and platforms, and the audience was pushed around in a hovercar, 1/2000th of an inch above the floor. This was the first time that Zaphod was represented by having two actors in one large costume. The narration of "The Book" was split between two usherettes, an adaptation that has appeared in no other version of H2G2. One of these usherettes, Cindy Oswin, went on to voice Trillian for the LP adaptation. The second stage show was performed throughout Wales between 15 January and 23 February 1980. This was a production of Theatr Clwyd, and was directed by Jonathan Petherbridge. The company performed adaptations of complete radio episodes, at times doing two episodes in a night, and at other times doing all six episodes of the first series in single three-hour sessions. This adaptation was performed again at the Oxford Playhouse in December 1981, the Bristol Hippodrome, Plymouth's Theatre Royal in May–June 1982, the Belgrade Theatre, Coventry, in July 1983 and La Boite in Brisbane, November 1983. The third and least successful stage show was held at the Rainbow Theatre in London, in July 1980. This was the second production directed by Ken Campbell. The Rainbow Theatre had been adapted
