It made 100 thousand worldwide and the same amount in dvd/blu ray. It had monster circulation through pirated copies as well so the movie isn't obscure by a long shot.
It was pretty successful.
The only movies that score big during its run time are those with established fan bases like those based off of books, or some other mainstream appeal. Anyone who appreciates films would not pay too much attention to solely US box office profitability.
