Here’s a surprising treat: a sweet, bracingly original, wholly entertaining film from writer director Victor Levin with a solid part for Anton Yelchin. In fact, every role is perfectly and inventively cast, which makes the movie almost hard to resist. The unusual plot involves aspiring writer Brian (Yelchin), who gets into a passionate love affair with a glamorous French woman (Bérénice Marlohe from “Skyfall”). Problem is: she’s married and she can only meet him between the hours of 5 and 7 (hence the title of the movie). As offbeat as the story may be, Levin makes it incredibly touching at times. What’s more, he has filled his movie with amusing, well drawn characters, especially Brian’s parents, played by the great Frank Langella and Glen Close. Is the overall result an unforgettable masterpiece? No. But “5 to 7” is an enjoyable modern-day fable for adults that will leave both men and women with a smile on their faces. How many movies can make that claim?
