"It has been recently reported that the loophole in German tax law has been revised. Starting January 2006, contributors to failed films will no longer be able to profit from failed films through a tax writeoff at the end of the year. This may well result in an end to Boll's film career, as it would make it impossible for him to capitalize on films that fail at the box office, resulting in a loss of investors."
