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.
The rule of thumb I've heard from accounting weenies in Hollyweird is that you take the total cost of the movie and multiply it by two--that is the box office take it must generate worldwide to make a profit, and that considers everything other revenue stream in the mix (since those streams tend to reflect a set percentage of the gross). The "movie reprint" of the book does not generate revenue for Hollyweird. The soundtrack revenue is small potatoes unless it generates some big hits.
The movie just wasn't very good--Hanks and Howard (who worked very well together on Apollo 13, so they can make a great movie when they're both passionate about it) just didn't seem to care, and it showed. They relied on the hype, instead of their own talent.
