Interesting noir that issues from an imaginative premise-- suppose we had a year that we could live all over again. So who wouldn't want that opportunity. Naturally, we could change our own actions to better optimize outcomes, but what about others-- would their actions have to change too.
The premise may even require the entire world to live that same year over so as to fit into the changes that ripple out from our own changes. Conceptual questions aside, the premise is simplified here into a rather clever soap-operish plot— namely, can sympathetic Sheila (Leslie) avoid killing her louse husband (Hayward) a second time around. That is, can she maybe just ignore his many provocations, given a second chance.
Instead of playing up occult aspects, the screenplay concentrates on revolving relationships among sophisticated show-business types. It's a good cast, especially an agreeably addled Richard Basehart. However, I'm not sure the sweetly gentle Leslie has the gravitas for a difficult role, especially for the wronged woman part. Still, she certainly wins our sympathy. Director Werker films in noirish style lending the visuals a suitably twilight quality. The ending too is appropriate, without obvious cheating on the premise.
The movie seems more obscure than deserved and I'm not sure why. It certainly made an impression on me on first viewing many years ago. I suspect the obscurity is because of a B- movie cast-- no matter how accomplished—and a non-studio pedigree. But whatever the reason, the film remains a thought provoking 90-minutes even this many years after.
