What was the first Harry Potter book written by J.K. Rowling to be adapted into a film?

Harry Potter and the Philosopher’s Stone was the first Harry Potter book by J.K. Rowling adapted into a film.

The film was released in 2001 under the title Harry Potter and the Sorcerer’s Stone in the United States and some other markets. Chris Columbus directed it, and the main cast included Daniel Radcliffe, Emma Watson, and Rupert Grint.

The story follows Harry’s discovery that he is a wizard, his arrival at Hogwarts, and his first confrontation with the mystery surrounding the Philosopher’s Stone. The production introduced the visual versions of Hogwarts, Diagon Alley, and other settings that became central to the film series.

The movie was a major commercial success and established the cast who would continue through the later films. A film adaptation of each of Rowling’s seven original novels followed, producing eight movies because the final book was split into two parts.
