> wikipedia says the film cost $190m, which seems reasonable for a film like this And you can add half of that again for the marketing budget.
I have always assumed those numbers are fudged, and included marketing. I don't really know much about the industry, or what it take to make a film like this, but $100m is enough to pay 1000 people 100k. Did this film take that many people, that long to make? I would imagine CGI is reducing a lot of expensive things (like blowing up aircraft, and expensive location shoots).
Just take a look at the credits at the end of a blockbuster movie to see how many specialized skills are required.
