Terrence Malick’s The Tree of Life is not the only recent film release that has probed the big questions and explored the wonders and mysteries of the natural world with a gloriously sincere, child-like awe and wonder. Werner Herzog’s astonishing, engrossing Cave of Forgotten Dreams has the same sort of existential curiosity as Life; the same operatic majesty. Both Malick and Herzog are explorers, philosophers, taking their cameras to the far reaches of the earth to create a cinematic meditation as interested in the science of the natural world as it is in the longings of the human heart.
