For those who don't know much about Uwe Boll:
(from wikipedia)
Boll is able to acquire funding thanks to German tax laws that reward investments in film. The law allows investors in German-owned films to write off 100% of their investment as a tax deduction; it also allows them to invest borrowed money and write off any fees associated with the loan. The investor is then only required to pay taxes on the profits made by the movie; if the movie loses money, the investor gets a tax writeoff.
