I heard that his supply of films was going to dry up soon because of a recent change in germans tax code.
Previously I think if you were a german who was making alot of money on stocks or whatever (and so would have to pay tons of income tax) and invested you invested in Uwe Boll and then the movie tanked you could write off several times the ammount you invested against the taxes you would owe, so you would end up coming out ahead.
It was to promote german movies/directors.
