If you're looking for a good seventies thriller, this isn't going to do it for you (try 'Chinatown' or 'All the President's Men'). However...
This is a masterpiece of masterpieces. For me, only a few dozen pictures (if that many) are even in the same league as 'The Conformist.'
It's about a young Italian fascist spy in the early 1930's who longs to fit into society. He takes his new middle class bride on a honeymoon trip to Paris. While there he is given a mission to assassinate an exiled Italian couple. That's the basic plot. But there is no possible way I can express the poetry of this film. The complexity is startling. I believe that I am a relatively intelligent man, but I'm going to need to see this many times before I will even begin comprehending it. Every shot contained a world of beauty and meaning, and an overwhelming amount of perfectly handled symbolism. The dialogue, the plot, and the images were bursting with literary and philosophical references which overlapped with one another to create a beautiful tangled web. I was in a daze after five minutes.
Like Bergman's 'Persona,' this is a film too many ambitious directors have tried but failed to make. It has all the ingredients for pretentious drivel; but it avoids every trap, and navigates the tightrope with casual confidence. I am in awe; but the awe only came after the film was over. Because while I was watching I didn't have time to analyze. I was too busy revelling in the beauty of an absolutely perfect experience.
The images are so surreal; like the most gorgeous nightmare imaginable. It blurs the line between utopia and dystopia. Everyone wears bold, outrageous outfits; every set is oppressively huge; the plot is melodramatic; the themes are ridiculously universal and profound (on some level I think it represents a disturbed retelling of Plato's Myth of the Cave); and it all works. I don't think I've ever seen such an audaciously ambitious film. Bertolucci is fearless. Or reckless. 'The Conformist' is a game of Russian roulette I can't believe he pulled off.
Also this may be the greatest cinematography I have ever seen (Believe me, I don't say that lightly). The director of photography, Vittorio Storaro (Apocalypse Now, Reds, Dick Tracy) is a genius. There is no way around it.
