Which J.K. Rowling book became the first Harry Potter film adaptation?

Harry Potter and the Philosopher’s Stone became the first Harry Potter film adaptation.

The film was released in 2001 and directed by Chris Columbus. Daniel Radcliffe played Harry Potter, Rupert Grint played Ron Weasley, and Emma Watson played Hermione Granger. The movie adapts Rowling’s 1997 debut novel and follows Harry’s first year at Hogwarts.

The film was titled Harry Potter and the Sorcerer’s Stone in the United States and some other markets, matching the American book title. This is a title variation rather than a different story. In the United Kingdom and many other countries, the film retained Philosopher’s Stone.

The adaptation launched an eight-film series because the final novel, Harry Potter and the Deathly Hallows, was divided into two films. The first movie introduced the visual versions of Hogwarts, Diagon Alley, Quidditch, and the main cast to a worldwide cinema audience.
