Studios have definitely gotten more conservative on the upper end, and the middle is nearly non-existent compared to the past.
Perhaps I'm showing my ignorance of the film industry. But, what stories require 10s of millions to make?
Any science fiction/fantasy movie with complicated sets and lots of effects for one. Any historical piece, with revives an older world. Anything involving lots of actors. Anything involving even one famous actor.
10 million dollars is at the absolutely bottom end concerning most of the famous Hollywood movies. Budgets around 70M-100M+ is the norm.
How much would it cost today?
Yes, animation has gotten better, but is state of the art animation always necessary? How much less does it cost to be a generation (or two) behind?
Suppose that Toy Story was first-released today, with its ancient animation. Who would care, and how does that affect box-office?
