Heyman's enthusiasm led to Rowling's 1999 sale of the film rights for the first four Harry Potter books to Warner Bros. Highly impressed by Rowling's work, he began the process that led to one of the most successful cinematic franchises of all time. Consequently, Heyman, who had originally disliked 'the rubbish title', read the book himself.

The book, Harry Potter and the Philosopher's Stone, was relegated to a low-priority bookshelf, where it was discovered by a secretary who read it and gave it to Heyman with a positive review. In late 1997, film producer David Heyman's London offices received a copy of the first book in what would become Rowling's series of seven Harry Potter novels. It is the fourth-highest-grossing film series, with $7.7 billion in worldwide receipts. Philosopher's Stone and Deathly Hallows – Part 2 are among the 50 highest-grossing films of all time-at 49th- and 16th-highest, respectively-with both grossing over $1 billion. Part 1 was released in November 2010, and Part 2 was released in July 2011. Harry Potter and the Deathly Hallows, the seventh and final novel in the series, was adapted into two feature-length parts. Production took place over ten years, with the main story arc following Harry's quest to overcome his arch-enemy Lord Voldemort. Michael Goldenberg wrote the screenplay for Harry Potter and the Order of the Phoenix (2007), while the remaining films' screenplays were written by Steve Kloves. Four directors worked on the series: Chris Columbus, Alfonso Cuarón, Mike Newell, and David Yates. The series was mainly produced by David Heyman, and stars Daniel Radcliffe, Rupert Grint, and Emma Watson as the three leading characters: Harry Potter, Ron Weasley, and Hermione Granger. A spin-off prequel series, planned to consist of five films, started with Fantastic Beasts and Where to Find Them (2016), marking the beginning of the Wizarding World shared media franchise. Pictures and consists of eight fantasy films, beginning with Harry Potter and the Philosopher's Stone (2001) and culminating with Harry Potter and the Deathly Hallows – Part 2 (2011).
