"Some blockbusters may be long, but at least people can reasonably watch it in one sitting. After all, some filmmakers couldn't care less about box-office numbers, critic reviews, or even the audience's ability to watch the entire work. Experimental movies challenge boundaries and conventions—a plot, character development, a runtime between 80 and 150 minutes, etc.—to the point where they hardly feel like part of the same medium as their theatrical siblings. Sometimes, this comes in the form of a multi-part series streamed on Netflix or aired on television over several days. But the following films—these mastodons, these titans—cannot be contained by even a serial format, and only the most dedicated viewer would be willing to see them through to the end. So here are the twenty longest films ever made, ranked from shortest (the word has never been used more loosely) to longest." - collider.com
