DNA (Red Dwarf) - Production

Production

"DNA", official full title "Do Not Alter", changed the continuity of the relationship between Lister and Kristine Kochanski. It is established that they had been dating and that she broke up with him, an idea which had been introduced in the novel Infinity Welcomes Careful Drivers. Doug Naylor and Craig Charles explained that Lister's infatuation with Kochanski, despite barely knowing her, was unrealistic.

With the tail end of production and finances running low the DNA ship's set was rushed and was not as had been expected. However the grungy looking corridors and rooms were better than nothing which may have been the case.

Paul McGuinness, a member of the effects team, wore the Vindaloo Mutant outfit. He also produced the three-headed corpse that Kryten and Rimmer discover on board the DNA ship. Richard Ridings voices the D.N.A. Ship Computer.

A cast-inspired gag came in at the end of the scene with Rimmer planning to clone himself from his own dandruff. Timing it just right into the rehearsals, Danny John-Jules sneezed on the microscope at the right moment - and it had just made the rehearsal.

Blue-screen techniques was used to produce the transformation of Lister to a 1-foot-tall (0.30 m) "super-human" man plus. Craig Charles was shot in front of a bluescreen to make him appear one foot tall, while this was added to the other crew's footage, who were also involved in blue screen, as they run by the small Lister.
