In the '60s and '70s it was a great period for American films because studios were still run by individuals who worked off the seat of their pants and went along with things. At that time, they were very uncertain about what to make because of the influence of television. A lot of really terrific movies were made. But then the studios gradually became more corporate and were owned by corporations and run in that way and now they're very nervous. You see what they make - sequels, franchises and try not to take risks.
