With production on an eleventh and twelfth series only weeks away, Red Dwarf fever is heating up with tickets for the live studio recordings harder to come by than a clean pair of Lister's socks. Over 14,000 people have applied to be in the audience this time around which proves the enduring popularity of a show that started life nearly 30 years ago as a low-budget space romp. It's come a long way from series one when producers had to drag punters from a nearby pub to help record the laughter track. Since then Kryten and Kochanski have been re-cast and Rimmer has become human again while Lister found himself drinking in the Rovers Return for a bit while he waited for someone at Dave to pick up the phone. But there are plenty of things you don't know about Britain's best-loved comedy sci-fi show. For example, what was Dave Lister originally called? Which other character was named after a butler? Who really blew up Red Dwarf? What happened in the lesser-seen Christmas special? Read on for all these answers and more.
