Film: Harry Potter and the Philosopher’s Stone
Filmed: 2000-2001
Released: 2001
Company: Warner Brothers

Harry Potter and the Philosopher’s Stone (known in some countries as Harry Potter and the Sorcerer’s Stone) is the first film of the series.

Warner Brothers bought the rights to turn JK Rowling’s first four books into films for just £1 million and spent $125 million on production. The film went on to earn almost a billion dollars guaranteeing that the other Harry Potter books would also be turned into movies.

Leavesden Studios was chosen as the location for filming after two British film industry officials offered Warner Brothers long-term use of the soundstages at Leavesden Studios and also changed labour laws to enable child actors to work more hours a week.

The production occupied the entire Leavesden site for a year and a half.

Sets built at Leavesden include:

• The Great Hall of Hogwarts
