The thread on art films prompted me to start this thread as I believe it deserves one all of its own. Swedish artist Anders Weberg plans to screen a 720 hour film in 2020 as his departure from experimental film. Yes, seven hundred and twenty hours. That's thirty days and nights of constant film screening. And after that screening, which will take place all over the world from one day onwards, the film will be destroyed and never shown again.

In Australia, we have a channel called SBS which broadcasts international content and world news, including a now-defunct show called Eat Carpet. Eat Carpet contained short films by creators from all over the world, many of them being experimental pieces or student films. Since then, I've always enjoyed experimental film, even if more in concept than execution.
It would be impossible to sit through a 720 hour film, and when it is destroyed, no one will be able to see the entire thing. But it would be pretty cool to walk into a gallery and watch half an hour or so over the course of a month, knowing that it has never been screened before and will never be seen again.
