Time Bandits (1981)

Intrigued by history but neglected by his parents, Kevin, an eleven-year-old schoolboy, gets the chance to make his dream come true when a band of six time-travelling dwarfs appears out of thin air in his bedroom. Having stolen the Supreme Being's one-of-a-kind map of time and space, the audacious time-bandits whisk Kevin off on an exciting journey to the depths of history, skipping from one era to another. Now, to further complicate matters, the dangerous arch-rival known as the Evil Genius is hot on their trail, bent on getting his hands on the precious map. But, who would have thought that Kevin's seemingly unexceptional room was the entrance to a mysterious wormhole and the portal to a marvellous world of adventure?—Nick Riganas
