'A Dog's Purpose', the surprisingly existential pup movie adapted from the 2010 novel written by W. Bruce Cameron, chronicles a dog's journey through four lives via reincarnation and how he looks for his purpose through each.

Lasse Hallström (director of 'Hachi, a dog's tale' and 'My life as a dog') weaves human emotion into a compelling film to remind you of the best times you had with your pet. It poignantly illustrates how much we need the love, affection and companionship of our furry friends.
