The challenge of film production has not changed… it is: “How do I get the money to make it all happen?”.
There are some recent new techniques, for example, using Patreon, Kickstarter, GoFundMe, etc. But those aren’t exactly “new” either, just enabled in a new way by modern tech.
Been reading a book about the director, John Frankenheimer, and a section on his movie adaptation of “The Iceman Cometh”. That movie is 4 hours long, and they had to cut material from the play to get it down to that length. One of the details of the production I found interesting was, the film was meant to be part of a series that were shown to audiences by “subscription”; i.e. you pre-paid for a “season ticket” to get exclusive access to see this and several other movies, specially made for this project and this audience. It’s perhaps similar in a way to the business model of “Fathom Events”, which I’m also fascinated by.
But John Frankenheimer was doing it back in 1973. It didn’t pan out back then, because not all the movies in the subscription series were of a scale and quality of “iceman”, so the subscriptions didn’t sell out, and regular Joes could walk in and buy a ticket the day of the screening, if there were seats available.
