Determining the original running time of the movie does not seem to be straightforward. The longest running time listed by the IMDb is 90 minutes but I am unable to verify this. When originally submitted to the British Board of Film Censors in 1972 the movie was refused classification. When resubmitted years later for video release the running time was 81:13, and some 42 seconds of cuts were insisted on. Assuming PAL speed-up the running time of that version must have been about 84:36, which is 0:25 more than the running time on this disc. I have no information as to whether that represents a difference in the running time of credits or whether it represents some missing footage. The cover claims that the film is uncut.
