What does it cost to make a Hollywood movie? How much money comes in? Here is a fascinating page:
This page shows, for example, that it cost $258 million to make Spiderman 3. It also shows the movie grossing close to a billion dollars worldwide.
Where does the money go?
A typical quote from the article: "The $70.2 million budget for "Signs" was dominated by the whopping $25 million Mel Gibson was paid for his role as "Graham Ness," a widowed ex-minister bedeviled by crop circles and an alien. In addition, the actor's entourage expenses totaled nearly $1 million, with $300,000 of that figure earmarked for the star's "jet allowance" and another $57,000 for a "chiropractor/masseuse." Gibson also received in excess of $1000 a day in per diem payments (the average daily "walking around" money provided for other on-location employees was $65)."
Here's something else about Spiderman 3. The run time for the movie is 140 minutes. The movie has 24 frames per second, so that means 201,600 frames for the whole movie. That works out to $1,280 per frame. So if you paid a group of artists $50/hour ($100,000/year), each artist could spend 25 hours drawing each frame of the movie.
