While fans would associate dinosaur movies with the Jurassic Park series, the sci-fi action flick 65 takes a unique approach to how Adam Driver's militant-minded Mills copes with dinos after crash-landing on Earth 65 million years ago.

Mills is actually from another planet where humans live, but that place is a paradise compared to somewhere where the monsters aren't in parks or cages.
