Harry Potter and the Sorcerer's Stone Trailer (2001)

Based on the popular first book of the series by J.K. Rowling, in the normal human world--the world of "Muggles"--Harry is a nobody, treated like dirt by the aunt and uncle who begrudgingly inherited him when his parents were killed by the evil Voldemort. A mysterious letter, delivered by the friendly giant Hagrid, wrenches Harry from his dreary, Muggle-ridden existence. It is an acceptance letter to the Hogwarts School of Witchcraft and Wizardry. Soon enough, Harry finds himself at Hogwarts with his owl Hedwig and in the world of wizards, he is famous as a survivor of the wizard who tried to kill him.
