Although made in 1939 this film does not appear to have been trade shown until 24 November 1942 (Kinematograph Year Book 1943). In the same source it is listed as being registered at the Board of Trade on 8 December 1942 and released in February 1943. The BBFC website does not have it as having been submitted for classification until 1951, when it would seem to have been reissued. However, and despite what it says above, in all contemporary listings the title is given as "The Body Vanishes", clearly its original release title. It is very likely, therefore, that "The Body Vanished" is only a title given it at a later date, perhaps when it was first aired on television.
Incorrectly listed in the British Film Catalogue (1895-1970) as "The Body Vanishes".
The poster for the sale of the "contents of the mansion" names "Tew, Tennyson and Walker" as the selling agents. The film was directed by Walter Tennyson and the screenplay was by Ian Walker.
