The Butterfly Effect is a 3 minute CG animated film Passion Pictures has made in partnership with Unity, the games engine developers.  Written and directed by Dan Sumich, he describes the film as, “A big dollop of bombastic fun.”  An ordinary looking guy wakes up one morning feeling the worse for wear and realises he’s run out of milk. As he drags himself out of the house to go and buy some, an extraordinary sequence of events draws him into a journey of mayhem on the streets of San Francisco.
