This was the first episode to be recorded without the
live studio audience. Technical difficulties of the actors playing other characters meant that the scenes would have to have been done twice. Instead the voices were dubbed over the scenes in
post-production and trying to match up with lip movements caused much mirth while recording. Chris Barrie, being an
impressionist, had no problems playing Lister, whereas Craig's portrayal as Rimmer was not as smooth. The final edit, with dubbed voices, was then played to a small audience to provide the
laughter track. The long chase sequence with Blue Midget and Starbug was overseen by effects supervisor Peter Wragg. Using his experience of working on shows such as
Thunderbirds, he had the model ships of Starbug and Blue Midget flying on hidden wires over a scaled landscape, Starbug eventually crashing into it. This episode has the only mention of the ship White Midget. This was a mistake on the part of the writers. In the Remastered version, Lister's voice is dubbed over so he says "The Midget" instead of "White Midget". Originally the new smaller ship that would be used was White Midget, a similar version of the Blue Midget, but then Starbug was created, which would be bigger and allow for more room to film inside. The large interior areas of Red Dwarf were filmed inside
Padiham Power Station. ==Cultural references==
