This one is probably the most confusing film out of all the ones on the list, but it’s also intriguing and brilliant. While Kubrick’s depiction of future technology was spot on, and his murderous AI was terrifying, it’s the ending when the astronaut Bowman travels through a vortex of lights and finds an older version of himself with the monolith. Then he’s turned into a fetus enclosed in a bubble of light and floats over the earth.

So, what does it all mean? No one really knows, but it’s inspired a great deal of debates and wild theories.
