The climax of “Strangers on a Train” is a feat, but it’s the interplay between the two principal characters and Robert Walker’s profoundly unsettling performance that resonate now.

Some say that Hitchcock’s pictures had a sameness to them, and perhaps that’s true — Hitchcock himself wondered about it. But the sameness of today’s franchise pictures is something else again. M any of the elements that define cinema as I know it are there in Marvel pictures. What’s not there is revelation, mystery or genuine emotional danger. Nothing is at risk. The pictures are made to satisfy a specific set of demands, and they are designed as variations on a finite number of themes.

They are sequels in name but they are remakes in spirit, and everything in them is officially sanctioned because it can’t really be any other way. That’s the nature of modern film franchises: market-researched, audience-tested, vetted, modified, revetted and remodified until they’re ready for consumption.

Another way of putting it would be that they are everything that the films of Paul Thomas Anderson or Claire Denis or Spike Lee or Ari Aster or Kathryn Bigelow or Wes Anderson are not. When I watch a movie by any of those filmmakers, I know I’m going to see something absolutely new and be taken to unexpected and maybe even unnameable areas of experience. My sense of what is possible in telling stories with moving images and sounds is going to be expanded.

So, you might ask, what’s my problem? Why not just let superhero films and other franchise films be? The reason is simple. In many places around this country and around the world, franchise films are now your primary choice if you want to see something on the big screen. It’s a perilous time in film exhibition, and there are fewer independent theaters than ever. The equation has flipped and streaming has become the primary delivery system. Still, I don’t know a single filmmaker who doesn’t want to design films for the big screen, to be projected before audiences in theaters.

That includes me, and I’m speaking as someone who just completed a picture for Netflix. It, and it alone, allowed us to make “The Irishman” the way we needed to, and for that I’ll always be thankful. We have a theatrical window, which is great. Would I like the picture to play on more big screens for longer periods of time? Of course I would. But no matter whom you make your movie with, the fact is that the screens in most multiplexes are crowded with franchise pictures.

And if you’re going to tell me that it’s simply a matter of supply and demand and giving the people what they want, I’m going to disagree. It’s a chicken-and-egg issue. If people are given only one kind of thing and endlessly sold only one kind of thing, of course they’re going to want more of that one kind of thing.
