Calamity the Cow is a 1967 British film directed by David Eastman and starring John Moulder-Brown and Elizabeth Dear.
[1][2] The film featured Phil Collins as a teenage actor three years prior to his joining Genesis.
The nicest touch is the Heath Robinson contraption which the children build from material they find in a junk-heap – an old bath and bits of a bedstead – to transport the cow to the show.
The slapstick ranges from flying paint from a can on a revolving horn gramophone to the predictable but vigorous action of Calamity biffing the villainous Kincaid into a water trough.
Fields and country lanes provide pleasant settings for an agreeable piece of children's entertainment.
