Undistinctive but enjoyable tearjerker: American doctor loves/loses/finds Vienna nightclub entertainer. The skillful screenplay mixes motherhood, medicine and the Iron Curtain, plus manages a few provocative digs at American male behavior. Rock Hudson and George Sanders give appealing performances. In the central role, German actress Cornell Borchers looks like Ingrid Bergman but lacks her warmth. A rich supporting cast includes a bit by Clint Eastwood . Old-fashioned, but done with some dignity.
