Origens (2014)

Four years in the making, Origins is a stunningly ambitious new documentary that challenges us to reevaluate our existence in the modern world, and embrace the simplicities that defined the beginnings of our species. "I believe to understand our present and to map our future, we have to go back in time," says Alan McSmith, an ecology instructor and a key interview subject featured in the film.
