Created by Rob Grant and Doug Naylor, Red Dwarf started life on BBC radio as a sketch called Dave Hollins — Space Cadet, but it was only when it transferred to BBC2 in the form of a totally re-worked thirty-minute sitcom that the premise really took flight.
The first episode sets up the series with Dave Lister (Craig Charles), a Liverpudlian slob with an obsession for curry that borders on the pathological, getting himself placed in stasis for the remainder of the ship's voyage after smuggling a cat aboard. While he remains un-ageing in a stasis chamber, Second Technician Arnold Rimmer (Chris Barrie) manages to neglect his duties and get the whole crew of the ship, himself included, killed by a blast of radiation. Two million years later and Holly (Norman Lovett), Red Dwarf's computer, lets Lister emerge from stasis as the last human alive. In order to keep him sane he also brings back Rimmer in the form of a hologram — denoted by an H on his forehead. The final member of the cast was Cat (Danny John-Jules), whose race had evolved over from the descendants of Lister's pet.
The first two seasons were fairly basic, ship-bound character pieces, but with the introduction of Kryten the cleaning mechanoid as a regular chracter at the start of Season 3, the series took a slight change of direction as the plots started to move towards a slightly more sci-fi based approach. At the same time the series started to gain a fan following as well as some impressive ratings. Season 2 also saw Hatty Hayridge replacing Norman Lovett as Holly.
Another change in the format of the show occured in Season 6. Red Dwarf had been lost (along with Holly), which meant the cast were travelling from one scrape to the next in Starbug — one of the ship's shuttlecraft. A major development was also on the cards for Rimmer who obtained a hard-light body, enabling him to physically interact with his surroundings.
By the time Season 7 came around in 1997, Chris Barrie had decided to leave the show, but before he did the series saw the introduction of Chloe Annett as a parallel-universe version of Kristine Kochanski, who had appeared in a number of the earlier episodes in the form of Clare Grogan.
The eighth, and so far final complete season, saw the re-introduction of Red Dwarf and also the return of the original crew when Kryten's nanobots recreate them. This was also a convenient way of re-introducing Rimmer, who had departed the previous year to take-over the role of galactic hero from the deceased Ace Rimmer.
Nearly ten years after Red Dwarf's apparent demise, it was announced in January 2009 that a number of new episodes had been commissioned for broadcast on Dave (a UK digital television channel) at Easter 2009. The three-part Back to Earth was accompanied by a making-of documentary, with the four programmes broadcast nightly from 10 April, and proved successful enough for a full season of six episodes to be commissioned later in the year.
All episodes of the show have been released on DVD.
