Kenneth More recalls in his autobiography, "More or Less" (1978), that the film copyright to "White Rabbit" was held by Hal E. Chester. Chester would not give permission for the BBC series to be made in case he decided to make a film of the book himself. However, the BBC (in British Law) can by-pass this, provided they make one transmission only of the subject and do not repeat the programme or sell it elsewhere. According to More, the then Controller of Features at the BBC, David Attenborough, decided to go ahead with the project, show it once and then destroy the tapes. It is therefore unlikely that any copy of this production still exists.
This was originally going to be a major theatrical release, and Richard Burton, Dirk Bogarde, James Mason and John Mills were all pursued by producer Michael Deeley. The proposed directors were Guy Green, Robert Siodmak and Roy Ward Baker.
