Word is that 200 megabucks will just about cover the cost of the rights to the property; it cost another 125 to produce after you prepaid the major players' royalties.
Figure that the movie's actual cost is 325 megabucks, and that it has to make 650 megabucks to actually make a profit.
Remember domestic gross generally only represents between 1/4 and 1/3 of the total revenue for a film (foreign, soundtrack, in this case probably a movie reprint of the book, cable sales, network TV sales, and DVD sales make up the rest... and tie-ins like toys and video games but I don't see that playing into the DVC bottomline). So a $200 mil domestic gross represents a total revenue of $600 to $800 million. It'll make a profit.
