Monty Python collaborator Neil Innes allegedly said of this movie, "The star was an alcoholic, the writer was an alcoholic, the producer was an alcoholic and the director was an alcoholic".
Due to its only having a running time of around 70 minutes, the picture in its debut theatrical release was supported by the reissue of a short, The Running Jumping & Standing Still Film (1959), starring Spike Milligan and Peter Sellers, which played before the feature. Both films are absurdist and "Goonish" in nature and also both in black-and-white.
Vivian Stanshall's initial response to Trevor Howard being cast as Sir Henry was that he would be "too upper-crust" but Stanshall later conceded after the end of filming that Howard was a better Sir Henry than his own characterization of him.
Trevor Howard once said of this film and his casting in it, 'Why on earth is he doing that film?" they'll say, and the answer is, because I want to do it. I might never get the offer to do such a thing again. People want to see it again and again because you can't grasp it all at once. It's wild".
