Watch full movie online. Tempus Fugit explores the effects of being able to travel back and forth in time in boring and insignificant installments – half-day to 6-7 days, at a stretch. But the point is, much like Butterfly Effect (the film – the wikipedia definition!), small, utterly insignificant, initial variations can/ may lead to large changes in the long term. This fascinating theory is clubbed along with an average-nobody’s seemingly inconsequential every day act becoming significant enough to save the world – to an incredible effect.
