Triangle

Watched this the other night. Probably the most clever film I have ever seen (possibly too clever as people who don't realise why this is happening think it's messy, which it isn't the film tries to confuse you). Took a lot of thinking, a rewatch and confirmation from the internet before I fully understood it. But when I did realise the full implications it blew my mind.

9/10 watch it. And see if you can figure out why everything is happening.
