(Flipped a coin between GQ and CS, and decided on CS.)
In America, films regularly cost in the tens of millions of dollars to produce, while the big-budget ones regularly exceed $100M. Now, I only have a few data points for foreign films, but it seems that the price is much lower overseas. Night Watch and Day Watch two Russian vampire/fantasy movies, were shot at about $4M apiece, and the latter in particular looks comparable to a middlebudget Hollywood production. Hero, although sporting a very different aesthetic than most American films, still has many of the expensive features of big-budget affairs - large, ornate sets, choreographed fight scenes, and hundreds of extras. It cost $30M.
What is the source of this disparity, and more broadly, how is all that money spent?
