Harry Caul played brilliantly by Gene Hackman plays a surveillance man who is listening to a couple through wire tap and discover that they might be murdered. This film has so many great quiet moments and terrifying moments. The film is really well acted and has some great music. The late John Cazale was also great as Harry's co worker. The film was timely, it came out around the same time as Watergate. It really it has a great intimate feel, a small arthouse film that Coppola made between the two Godfather films that still stands up today. I recommend it to any film fan looking for something different and wanting to discover yet another great film from the 1970's.
