NIght Moves falls into that category of movies that was not so loved when it came it but since time has passed, people have come around to it. It also benefits from being from that new golden era of cinema, the 70s, where the films showcase a gritty side to characters, often played by some of the best anti-hero actors of all time -- Hackman, in this case. Night Moves is a good movie and a lot of fun but it has some limitations which keep it from being more than that.
First of which, the story really doesn't make sense. It's clear when the case is more or less solved about an hour in that the movie is really going to be about something else. In this case, it's more about Hackman's character, a guy who despite his love of things like chess, can't seem to really figure stuff out. So we are taken through his marriage, his wife's infidelity. an attempted reconciliation, etc. All that stuff is great for a great actor like Hackman who makes you feel how lost he is.
The problem is that the ties that connect that to the real story, that of the art smuggling, which is the real mystery, are very thin. Also, the ties that connect the plot points of the smuggling story are very week. Too much coincidence, too many people happen to be exactly where they need to be. Too much crossing the country - - LA to Florida in the blink of an eye. One second Gene Hackman is chasing James Woods around LA on a motorcycle. The next scene, he finds him in Florida.
I read that the film was shot in 1973 and then shelved until 1975, meaning that there must have been issues with it then. There must have also been a lot scenes cut, because a lot is in there, it's just hidden very deeply with no way to get at it. I think this is a film to check out and enjoy for some very good elements. I just don't think we can put our blinders on and make it a 70s classic. Good film. Worth a watch.
