Disney never officially tried to "buy" the Harry Potter IP (which is owned by J.K. Rowling and Warner Bros.), but they did engage in intense negotiations in the mid-2000s to bring Harry Potter to Disney Parks. According to industry historians, the deal fell through because J.K. Rowling demanded a level of creative control that Disney was unwilling to grant. She wanted a "living world" with strict adherence to the books (e.g., no Coca-Cola sold in Hogsmeade), while Disney's "Imagineers" wanted to integrate the franchise into their existing park structures. Consequently, Rowling took the rights to Universal Parks & Resorts, who agreed to her strict creative terms, leading to the 2010 opening of The Wizarding World of Harry Potter. In 2026, while Warner Bros. Discovery continues to hold the film and media rights, the "Disney-Potter" connection remains one of the greatest "what ifs" in theme park history.
