MOS had of official budget of 225 and they spent over 100 mill marketing. The true cost like all studio movies will be a little higher and a lot of those final grosses came from China, where the complex process means only 1 in 4 dollars comes back as revenues to the studios). So even OFFICIALLY their return of $660 was a break-even at best, though I suspect they lost some dough. Hence, there is no plans for another Superman solo movie between now and the end of the decade when even the modest losses of Batman Begins led on to an immediate sequel.
Batman Returns was interesting because it didn’t make any money (despite the high quality of the product in my opinion) and Schumacher was brought in to save the franchise, as hard as that is to believe now. It cost over 80 and they spent a lot on marketing so the grosses meant it didn’t see a profit, but the BIG problem was that the toys were a tragedy after the triumph of the Batman toys, which grossed even more than the record-smashing movie numbers. Batman Forever (which I have a weird fondness for) only made a very, very modest profit (cost 100, marketing over 50, worldwide gross of 330), but the toys did gangbusters and Joel S was a hero at WB for steadying the franchise as far as people were concerned. So even though Forever only made a modest profit it’s still in profit, which is why it’s one of the four.
Interesting aside: Batman movies only REALLY make a huge profit when The Joker is in them (66, Tim Burton’s 1989 and 2008). Begins made 370, Dark Knight made over a billion and Rises, I think, owes the billion plus to the momentum from Dark Knight in a lot of ways. My theory and I say this as a HUGE Batman fan: Audiences love The Joker more than Batman.
