Technology has always been a big part of moviemaking. Film cameras were themselves an invention, and artists and technicians have been inventing and improving technology and techniques to make better and more elaborate movies ever since. But what about great movies that don’t just use technology? What about the great movies that are about technology themselves?

Heck, every film where there’s a wheel arguably involves some sort of technology. Science fiction, as a genre, is also hugely based on fantastic visions of machinery advancements.

With that in mind, here are the best movies that speak to mankind’s relationships with the wonderful—and terrible—machines and devices we’ve created.
