One night, Albus Dumbledore and Minerva McGonagall, professors at Hogwarts, with Rubeus Hagrid deliver orphaned infant named Harry Potter to his remaining relatives, the Dursleys.
Ten years later, Harry Potter (Daniel Radcliffe) begins receiving strange letters by owls. He and the Dursleys escape to an island from intrusive letters. There appears Hagrid and informs Harry that he is wizard and his parents were wizards too. Harry has been accepted into Hogwarts, a school where young witches and wizards are taught magic.
Hagrid also tells Harry that his parents were killed by an evil wizard called Lord Voldemort when he was just a baby. Because Harry's mother let herself die to protect Harry, Voldemort could not kill Harry and died instead. Harry is well-known as "The Boy Who Lived".
Alnwick Castle was used as a principal filming location for Hogwarts.
At Hogwarts, Harry begins learning magical spells, plays Quidditch. One night the stair cases change paths leading Harry, Ron and Hermione to the forbidden floor of Hogwarts. There is a giant three-headed dog named Fluffy which guards the Philosopher's Stone, as it turns out later. Harry suspects that the Potions teacher Severus Snape is trying to obtain the stone to return Voldemort to physical form.
One day Hagrid reveals to Harry, Ron and Hermione that Fluffy will fall asleep if the music is played to him. The trio decide to find the stone before Snape does. They discover an already asleep Fluffy and face a series of obstacles before Harry find the stone.
After getting past the tasks, Harry find out that it is the Defence Against the Dark Arts teacher, Professor Quirrell, who is trying to claim the stone. Snape had been protecting Harry all along. Quirrell removes his turban and reveals that Voldemort's face is living on the back of his head. Harry manages to get the Philosopher's Stone by looking into a magic mirror. Voldemort/Quirrell tries to kill Harry but because Harry is still protected by his dead mother's love, Quirrell cannot touch Harry and he turns to dust. Voldemort's soul escapes.
Harry recovers in the school's hospital wing. The headmaster, Professor Dumbledore explains him that the stone is destroyed and his friends are safe. He also reveals the cause of defeat Quirrell by Harry: because of his mother Harry has love-based protection from Voldemort.
Harry, Ron and Hermione are rewarded with house points for their heroic performances. Harry returns home for the summer, happy to finally have a real home in Hogwarts.
Producer David Heyman searched for a children's book for well-received adaptation. [1] His staff decided that Harry Potter and the Philosopher's Stone was a "cool idea".[1] Heyman suggested the idea to Warner Bros.[1] In 1999, Rowling sold the company the rights to the first four Harry Potter books for a reported £1 million.[2]
