Made in 1972 this film has all the humour of the lovely Spike Milligan and Michael Bentine (who also make an appearance). It’s very Goonish and very Pythonish, which is not suprising as it was written by John Cleese and Graham Chapman, along with ‘additional dialogue’ from John Fortune and John Wells. John Wells incidentally plays the part of Owltruss ??? How they came upon this name is a mystery, though he is rather a strange character.
