The Back of Beyond has perfectly good production values–it takes place in the West Indies, at a British protectorate island (it’s a Maugham adaptation, where else would it take place)–but director Ripley doesn’t have much going for him.
It’s a play on TV, sure, but he doesn’t know when to use his close-ups and when not to use them. He’s got a fine lead in Alexis Smith as an unfaithful wife (cavorting with her husband’s assistant) and George Macready is great as the husband. Even though Ripley’s direction lacks subtlety, the strange relationship between the couple comes through in the performances.
And Smith does get one rather good monologue towards the end.
Once it becomes clear nothing interesting is going to happen in Beyond, it becomes tiresome. There are all sorts of innuendoes no one ever delivers; Ripley’s not an imaginative director. His actors are good though.
