It Shouldn't Happen to a Vet (in the United States also known as All Things Bright and Beautiful), is a 1976 sequel to the 1975 film All Creatures Great and Small.

[2] The story continues where All Creatures Great and Small ended, and follows the lives of James, Helen and Siegfried from 1938 until the outbreak of war.

[6]John Alderton was offered the part of Herriott in the television version of All Creatures Great and Small but turned it down.

[7] According to Herriott's biographer, "John Alderton was far and away the best of the three actors who portrayed Alf on screen, with a boyish but twinkly British charm that managed to make him appear shy and gauche without ever being wet or pathetic.

"[8] According to Filmink the movie "had a better actor to play James Herriott (John Alderton, the great lost British film star of the 1970s) than All Creatures Great and Small, but didn’t have as compelling a story – it started with Herriott already established in Yorkshire and in love, and didn’t add anything much new.
