Forget the fact that The Conversation didn't get the headlines or awards of the Godfather. No flashy razamatazz, just quality writing, directing and acting, not least the finest performance of a glittering career by Gene Hackman as the intensely private and paranoid sound recording expert Harry Caul, who uncovers a plot, but finds himself digging too deep and losing control. The subtlety of Hackman is evident from the spare dialogue - he says little, but expresses his character's thoughts and emotions as though you could read his mind.
This is an intense, smouldering character study with a brilliant twist, fully deserving its place in my personal top 10 films of all time. As with all the best films, it stands repeated watching to appreciate the hidden depths within its apparently simple architecture.
Furthermore, at this price it is an absolute bargain. Buy and enjoy!
