You people are so spoiled.
A superhero movie doesn't cross 1 billion and you're like omg itz teh bomb.
Get real. Most studios would kill for a movie that makes around 800 m WW.
By the time they get around to dvd sales and tv rights Sony would've made 250 million. If the sequel is good Sony can expect much more since ASM2 will likely make more globally.
And guess where that 250 million goes? Into ASM2. And if the profits stagnate even harder after that? Does it pay for ASM3?
No doubt they are going to make a nice chunk of change. But what happened to that long term investment that was supposed to pay for itself? Going into more Spidey movies until one is unprofitable?
I don't think you can scale down budgets significantly for sequels either. You actually do need to bring in a good 300-400 million with this movie when all is said and done. Box office wise, it appears they will fall well short of that figure.
