Ooh, so sorry we didn't have crazy over-the-top action scenes and expensive CGI that today's ADD audience can't live without.
The "ADD" thing is lame, has gotten old and is a lie anyway. Fact is, if you don't spend a lot of money to make and promote big action movies you can't get enough of any kind of people of any age, background or condition to pay to see them in a theater.
There's nothing that was done in Goldfinger that can't be done on HBO now, and all that requires of anyone is a flick of the remote.
Ah, but here's my question. Would audiences stop seeing the latest superhero movies if they all had their budgets slashed by 50%? I don't think people care about special effects nearly as much as studios think they do.
Yes. All that movies have to sell now is spectacle. The first studio to start raising the budget again to show the audience something that everyone else isn't showing them because (for some unknown reason) they've decided to reign in the budgets will blow the others out of the theaters and start the escalation again.
If the studios could make the kind of money that keeps them in business and justify the financial risks they undertake while spending a lot less to achieve that, they would. Fewer movies and bigger movies are made now than fifty years ago, but the percentage of films that actually lose money for their investors is also a great deal lower, for many reasons.
