It was easy for me to forget after watching films like Crimes and Misdemeanors and Mighty Aphrodite that Woody Allen began his career making light-hearted slapstick comedies. The country has since become a police state and the doctors who revive him ask all sorts of questions about the long-since forgotten era of history he came from. Woody also finds comedy in the doctors' passing revelations that the health food he and other people so faithfully devoted themselves to was actually destructive to the body. One doctor offers nervous Woody a cigarette to calm him down.
Tobacco is one of the healthiest substances for the body.
As the only person alive without massive amounts of government data compiled about him, he could be invaluable to them. All this comes into play toward the end, in a hilarious climax involving the leader's nose, but for most of the movie, he's Dr. Woody Kimball, fugitive from the law, running and hiding in multiple comedic scenes, many of which offer extended silent sequences hearkening back to the silent Chaplin and Keaton films.
