On the DVD: A suitably eclectic not to say eccentric collection of extra features makes this a wholly satisfying two-disc set, neatly packaged in a fold-out slipcase. On the second disc there's an hour-long "making of" documentary from 1992 featuring contributions from the cast and crew, including Douglas Adams; and then there's even more in a 20-minute section entitled "Don't Panic!". A fascinating behind-the-scenes peek at filming as the clock runs out on studio time and a look at the recording of the original radio series complete the first part. Then navigate to the "Outer Planets" to find outtakes, a deleted scene, Zaphod's animatronic second head on Tomorrow's World and Peter Jones's witty and shambolic introduction to the first episode, plus more besides. The series itself is presented in standard 4:3 ratio and Dolby stereo.
