Speaking of clones there’s a super-good clone movie everyone needs to check out called Moon. A miner arrives for his 3 year contract to work alone on a moon base, waking up from cryosleep upon arrival. He goes out and while mining finds a crashed mining machine just like the one he’s driving, and searching the wreckage finds an exact clone of him just barely alive. He brings the clone back to base, just for the clone to reveal he’s been there for almost three years already so the other must be the clone! Anyways highly recommend, and your comment made it pop into my head
