Do animals feel the same emotions as human beings? While many animals seem to exhibit outward signs of happiness, anger, or fear, do they actually feel joy or sorrow, or is this merely our interpretation of other behaviors? And do they possess more complex feelings such as love or jealousy? The documentary Why Dogs Smile and Chimpanzees Cry takes a look at the emotional life of animals, and attempts to offer an informed answer to these and other questions about the internal life of our four-footed friends. Why Dogs Smile and Chimpanzees Cry was produced for the cable television network The Discovery Channel and was narrated by Sigourney Weaver.
