The film that could become a firebomb of controversy in Germany may be extinguished by politics a month before its release. “Romper Stomper,” the Australian skinhead punch-fest, has been virtually prohibited by the refusal of ratings board FSK.Without an “under 16″ or “under 17″ rating, “Romper” cannot be shown on TV and has virtually no chance of being picked up by already squeamish exhibitors. The only reason for the refusal given by the FSK yesterday was that “the film goes contrary to FSK Article 2,” which prohibits films that incite racism and anti-democratic principles, i.e. fascism. “Romper Stomper,” already creating controversy in Australia, tells the story of a group of neo-Nazi skinheads from the inside, without taking a stand against fascism or violence. It has been compared to “A Clockwork Orange.” With the recent wave of neo-Nazi violence sweeping parts of Germany, distrib Delta in Berlin has been apprehensive about accusations of “incitement to violence and racism.” However, the film is less violent than many rated films, and has been well received at many fests.
