A little man called Mr. Once-upon-a-time always interrupts everyone's storytime, so the townspeople decide to throw him in jail, only to find that their stories aren't as amusing anymore. Mr. Once-upon-a-time is a wonderfully comical story about storytelling. This is the third collaboration from Rémy Simard and Pierre Pratt that delivers a high-spirited playfulness reminiscent of the critically acclaimed My Dog is an Elephant.
