Idiocracy

This film is ridiculously funny, but it's not as funny as it is scary. This comedy is based around the theory that in the future humans will have de-evolved into unintelligent idiots. The protagonist, played by Luke Wilson, is cryogenically frozen in the present and wakes up to find that humanity has taken more than a few steps backwards and he is the most intelligent person on the planet. The funny part is the protagonist isn't very smart himself. This film is a political and ideological commentary on human behavior.
