Jon Amiel’s Sommersby (B) is a soapy, post-Civil War-era retelling of the French film Return of Martin Guerre about a war hero (Richard Gere) who returns to his southern home and to his wife (Jodie Foster) and son — but the returning hero may actually be an imposter. But could the guy who returned actually be an improvement over the hubby from before? The script is a bit overwrought and many twists far-fetched, but the actors give it their all, and the production values are strong. Danny Elfman provides a rare and effective romantic score. It’s pretty likely you’ll be hooked to the central couple’s story and on the edge of your seat about how it turns out.
