"Gilda" is a great nasty film noir, in which Glenn Ford isn't quite man enough to take on Rita Hayworth, and she keeps flaunting it in his face. Will he step up to the plate... or burst into tears? If you're a fan of that movie hoping for more of their unique sado-masochistic chemistry, forget it. "Affair in Trinidad" is a third-rate knockoff of Notorious, but director Vincent Sherman is no Charles Vidor. In fact, he's nobody. The stars don't make fools of themselves as they did in their ludicrous "Carmen," but duller isn't necessarily better. She throws her hair around energetically, but years of hard living had taken their toll, and you know Hayworth is in trouble when you find yourself wondering if she's wearing a wig. "Gilda" was Ford's finest hour, maybe because his usual scowling tough guy act was framed up as a paper-thin cover for sexual ambiguity. Here, he looks like he can barely keep himself from stomping off the set in disgust. You're luckier than he was: you have a remote.
