En busca del fuego

This is an extremely overlooked film many people should learn about. First, it tells you a very complex story without a single line of dialog successfully.

Second, the story is universal: Every civilization on earth can pick up this film and understand it, because it goes to the most basic, primitive issues of a species (mainly, survival). Third, it makes the beginning of man interesting. Fourth, it reminds us we were once as savage as any other animal on earth.

Fifth, it's like no other movie you've seen before. That one I can guarantee you.
