Are there any good movies about early humans (e.g. cavemen) that aren't a comedy?

I think this 'pre-civilization' time period of human history is very interesting and I'd like to see this portrayed in a movie. However, every movie I've seen about this was a comedy mostly not based on anything accurate about that time. Not that it's inherently bad, but I'd like to see a more serious approach.Do you know any that you can recommend? via /r/movies https://ift.tt/zsFtIbP
