Yes, it is not doing well. So far it has only brought in about $65 million in the states and it cost $110 to make, I figure it's going to make it up in DVD sales.
There has been a lot of disappointment this summer at the box office, a lot of films have performed well below expectations, especially those with big name stars.
And let's not forget the foreign markets. Not necessarily this one, but a significant number of American films now make up over half of their box office gross overseas.
