And there was $10 million in marketing, so it was around $49 million all together. (Joss made it for $39 million)
It made $38 million worldwide, but the DVD sales are pretty good. It sold $2 million copies as of Jan 31, (at the retail price of $20.00 will say, that is $40 million) and $9 million in rentals.
Sooo it grossed $87 million all together making $39 million. I don't think that is enough for a sequel or another Joss movie. I think I answered my own question.
