SLEEPER is rarely given proper credit (only one person has mentioned it on their list in this thread). For me, it's peak Allen comedy. Certainly Allen's most brilliantly-realized "pure comedy" film, and possibly one of the most visually and thematically ambitious comedies ever conceived. It was also the first Woody Allen film I ever saw as a child, so it holds a special place in my heart. But that's not why I laud the film. It simply is a masterpiece.
Firstly, the concept itself is hilarious: a nebbish granola-loving vegetarian wakes up 300 years in the future. A classic fish-out-of water tale, but with an Orwellian twist that raises the stakes to keep the tension high. As an "alien" from the past, Allen's character Miles is bewildered to awaken in the future, but barely has time to come to grips with this fact before having to embark on living life as a fugitive. He can never relax - Big Brother is around every corner. Does he keep running, assimilate into society, or join the resistance?
And then the there's the stylized visuals...dear lord, the visuals! The use of existing architectural wonders such as 1963's Sculptured House by Charles Deaton in Genessee, Colorado really sell the world-building of this film. The starkly retrofuturistic interiors with absurdly non-ergonomic furniture provide laughs while fleshing out the message that humankind has lost touch with itself. The Orgasmatron pushes this theme to its funniest, yet most heartbreaking conclusion: Technology has taken the place human connection, and we no longer need to lift a finger toward our fellowman -- not even to experience the pleasurable intimacy sex. Alienation is total.
Now let's talk about pacing--it never let's up. There is a constant moving-forward due to the pressure of having to remain on the run, and also a mounting sense of urgency that someone must Do Something Soon to wrest society from its hypnotic complacency. There are, to be sure, deliberate pauses for visual gags to unfold, like when he is hungry and discovers a garden of gigantic vegetables, and has trouble running away with the enormous crops. But even then, these detours are short, and lead us always to the next plot point.
Diane Keaton (Luna)'s character arc from spoiled, lazy, detached narcissist to tree-dwelling rebel is a joy to behold. The see-sawing of where Miles starts out and where Luna end's up -- the Freaky-Friday switcheroo that their characters do -- is so frustratingly great.
The dialogue in the film is steadily hysterical. Every scene is filled with classic, quotable one-liners as well as cleverly underscoring the unique traits of each character. Take for instance, when Miles and Luna are disguised as doctors and are pulled aside and asked to clone a nose, and Miles attempts to to stall: "I think what the computer is failing to take into account is what I call 'The Pinocchio Effect,' which states that the square root of the proboscis is equal to the sum of the sinuses....over seven." Who else could come up with something so crazy? Then there's Luna (Keaton), previously shown to be not so smart. She also attempts to stall the operation, though in a less verbose way: "Give us a moment. A medical moment" which I bet Keaton totally ad-libbed. (My friend and I still say "Give me a moment -- a medical moment," to this day.)
Finally, the ragtime score, as per usual with Allen's comedies, punctuates and enhances the absurdity of the proceedings.
Everything about SLEEPER is visual, intellectual, and comic poetry in motion. If you haven't seen it, coming in at a tight 89 minutes, it's well worth the time.
