"Night Moves" was a surprise to me. I assumed it could be a far more simple mystery/action film, but the whole thing caught my attention and really amazed me. What a great study in murder, infidelity, cruelty, sex, and relationships between strangers. A kind of film noir with dark overtones and a slow but effective suspense, the story starts as a simple investigation about a runaway teenager, but grows more and more into a complex drama plenty of unexpected twists. Gene Hackman is superb as the rude detective, the rest of the cast is also in fine form, but the real shock is to see a very young, hot (and naked) Melanie Grifith doing a terrific performance. James Woods is also here, with less impact but great to see too. An excellent film, one of the finest 70's underrated movies.
