Not a movie, but:
Two French guys travel far and wide while killing and maiming millions, taking drugs made by their elderly friend, utterly destroying the porcine populations of everywhere they go, committing serial robbery from liquor stores, and permanently ruining several historic monuments. They are looked upon as heroes by their peers, and they are declared to be criminals by every government they come into contact with except for their own. Hundreds of people, some extremely famous, repeatedly try and fail to stop them, most dying in the attempt.
