The makers of Doctor Who have long used codenames and anagrams when they want to keep something from us. Most recently, Jenna-Louise Coleman revealed that she had to pretend she was auditioning for something called “Men on Waves”.
She told Radio Times: “When she was auditioning, Karen Gillan had been given a codename - Panic Moon, which is an anagram of Companion - so I worked out that Men on Waves is an anagram of Woman Seven, because this is the seventh series. Weirdly, seven is my lucky number and this is my seventh job.”
Back in 2005, the very biggest secret of them all was the show itself: everybody wanted to know what the revived Doctor Who would look like and the production team went so far as to relabel the very few videos that had to leave the office.
Instead of “Doctor Who”, they were labelled with an anagram: “Torchwood”.
In 1988’s Remembrance of the Daleks, the production team knew full well that listing a character as being played by Terry Molloy would tip off fans that Davros, creator of the Daleks, was back. So in the cast list they provided to Radio Times for that week, they billed the actor as Roy Tromelly.
