It Shouldn't Happen to a Vet

The diary of a vet by James Herriot made into a film before the television series. It still has the Hillman Minx but different actors and the vet is already married. It's supposed to be set in the 1930s but the vet has rather long (Beatles style) hair, and in an early scene his wife has flares. Despite being made by the conservative Readers Digest, it features the famous vet scene with the vet's arm right up a heifer's nasty, and Tristan crashes the car when he's on the sauce, but he doesn't quite have the English hopelessness of Peter Davison (in the books Tristan is a bit of a ladykiller by the way).
