Well, if Sony ever sells the rights (which I doubt they ever will), it would be a huge, big number probably, although for Disney, it'll be peanuts.
@spiderman2: they wouldn't be the first studio hoping for huge results with a movie and being disappointed, it seems WB was pretty disappointed with MOS when on paper it seemed like it did very well, turns out the total costs of the movie amount to 619 million dollars, pretty far from the "reported" production budget of 258 million dollars, they only made a profit of 42 million dollars.
Discussing the budget of TASM2 is far from being as simple as it is being made out to be.
