The review

A game warden's wife raises an orphaned lion and the cub grows into an animal who cannot stay in the house. The work of the film is teaching her to hunt so they can let her go. The temptation, which the film understands, is to keep her as a proof of the bond. The bond is real. The bond is not a reason to make a lion into a pet that will fail the moment the people are gone. They do the harder thing.

A child old enough not to be destroyed by the parting can watch it. Tell them the parting is the point before you start if they are tender. Ask what the couple gave up by succeeding. The answer is the daily presence of the animal they love. A house that only knows stories in which love means keeping will fidget, and the fidget is useful. One of the cleaner family pictures of 1966, and quieter than the year's spectacles. The quiet is a couple doing a job for an animal that cannot thank them in a way they get to keep.
