Nice guy Quimby (Richard Basehart) plots to murder the lunkhead who stole his wife (Audrey Totter), and meets nice girl Mary (Cyd Charisse) along the way. When the lunkhead turns up dead, things become complicated.
Audrey Totter was delightfully nasty as the unfaithful wife. She drips with venom. Totter built a career as a femme fatale, her look being perfect for the woman of danger. When those roles dried up she transitioned to television. I had only seen Cyd Charisse in Singin’ in the Rain, and thought of her just as a dancer. She did no dancing here, and was quite charming in her good girl role. William Conrad (TV's Cannon) has a sizable role.
The tension in the title refers to the amount of tension the investigating officer needs to apply to suspects before they break, like with a rubber band. It’s a corny but forgivable analogy. As we know what happens pretty early on, this isn’t much of a mystery. The real star here is the delicious dialog which makes every scene pop. We care about the protagonists, hate the antagonists, and the story sizzles when it needs to.
Were I to criticize, it would be how the protagonist must act stupid so that the story can progress. The entire film would have been wrapped up in the second act had they just answered the police’s question. Also, the ending wasn’t quite as smart as it could have been.
That aside, Tension was an absolute delight to watch. Tight dialog, great characterizations, and excellent acting. The whole thing simply popped. AMRU 4.
