, Arnold Rimmer, Kryten, and the Cat take a Starbug to investigate the wreckage of a ship called SSS Esperanto on an ocean-covered moon. The group discover that the ship was conducting marine seeding experiments that included accelerating the evolution of life on the planet, but find that all life onboard had committed suicide. Kryten discovers this was caused by mutated form of squid ink that contained a hallucinogenic nerve toxin, and that the suicides were caused by the toxin giving its victims severe depression, stating that he, Lister and Cat are now being affected by it. Finding that the ink may have come from the only remaining life form on the moon, a giant squid, the group attempt to escape it, but crash Starbug and are killed in the explosion. A moment later, the crew awaken from Artificial Reality machines and discover that they have been playing "Red Dwarf – The Total Immersion Video Game", and that the length of time has left them with temporary memory loss. The group discover who they are in time—Lister is Voter Colonel Sebastian Doyle, head of the secret police in a fascist state; Rimmer is Billy Doyle, Lister's half-brother and a tramp; Cat is Duane Dibbley, a dorky human; and Kryten is Detective Jake Bullet, a half-human traffic officer. The group feel despair at finding out who they are, Kryten initially being pleased at his "real" existence until he is forced to take a human life to save another, and prepare to commit group suicide. However, before they do this, Holly manages to wake them up, revealing that they are still onboard Starbug—their crash and the "reality" they were in were just a hallucination. Kryten deduces the squid was the culprit, developing a defence mechanism that allowed it to use ink spread despair on any attacker and make them commit suicide. After Holly confirms she killed it, Lister determines the Esperantos crew were punished by the squid for playing god, as the group return to Red Dwarf.
Production
"Back to Reality" was the first script written for Series V, and it was thought of at the time that this would be the final series as there looked like there would be a cast availability problem: Chris Barrie was starring in the increasingly popular sit-com Brittas Empire, while Robert Llewellyn was appearing in Red Dwarf USA, a Red Dwarf pilot commissioned by American production company NBC, with the possibility of being committed to that for several years. Although the budget for the series had increased, certain sets were still able to double for different scenes. The corridors of the holoship, from the episode of the same name, were adapted for the Artificial Reality suite. The interiors of the SSS Esperanto were filmed at Sunbury Pumphouse, and were the only scenes directed by Juliet May. Several model shots of the Despair Squid were filmed but it was decided that they did not work well. Instead, a superimposed shadow was used to illustrate the squid closing in on Starbug. Lenny Von Dohlen, known for appearing in Twin Peaks, agreed to appear as a policeman after speaking with former guest star Frances Barber. The episode also featured a new Red Dwarf crew for the new Artificial Reality game. Anastasia Hille played Kochanski, David Lemkin played the Cat, Julian Lyon played Rimmer, John Sharian played Lister and Scott Charles Bennett played Kryten. Timothy Spall and Marie McCarthy played two employees, a staff worker named Andy and a nurse respectively, attending to the 'Red Dwarf Total Immersion Video Game'.
Reception
The episode was originally broadcast on the British television channel BBC2 on 26 March 1992 in the 9:00pm evening time slot, and is generally considered to be one of the best of the entire series' run. It has been described as a "classic episode questions our certainty about what is real. It has us believing that what we thought was real was only a simulation of dream, only to reveal later on that the waking up was actually a falling asleep." Another review said that it was "one of the best and most clever episodes ever made—here we see the birth of Dwane Dibbly—'nuff said." Rob Grant has described this episode as one of his favourites: "that was a show I was sorta in the director's chair for and personally it's a gobsmackingly good show in terms of RD shows." At the end of 1992 the episode helped Series V gain a nomination for an International Emmy Award, and in 1995, following a BBC viewers vote, it was repeated on 22 December 1995 as 'The Best-Ever Red Dwarf'. The episode had proved popular enough for the BBC to ignore the original running order and use the popular episodes from Series V to maximise sales of the video releases. The episode that featured on the other Series V video release being "Quarantine".
