"Detour" is far more famous. And it's probably better. But this strange little movie moves as inexorably to a terrible end as "Detour" does.
Charles McGraw was an excellent actor. He is fine here as "Honest Joe" Peters. He encounters Diane, a woman he never ought to have encountered, on a plane ride. He is a straight-arrow insurance investigator. She is looking for a rich man. She knows he isn't rich and she is not really painted as a villain.
Joan Dixon plays Diane in a deadpan manner. She is pretty and has a soft, rather high voice. Maybe she was someone's idea of an Elizabeth Taylor lookalike. There are similarities.
Everything is understated. Yet it's a tough movie. And it's powerful, and sad.
