The lowest-grossing film in the Wizarding World franchise is Fantastic Beasts: The Secrets of Dumbledore, the third entry in the Fantastic Beasts spin-off series. Released in April 2022, it marked the franchise’s first box-office flop, grossing just $407.1 million globally, equivalent to around $438.6 million (£341m) in 2024 dollars.
With a production budget of $200 million (£148m), industry experts estimated that the film would need to gross around $800 million (£594m) to break even when accounting for additional costs such as distribution and marketing. However, it fell significantly short of expectations, with everything from the film's execution to controversies surrounding Harry Potter creator J.K. Rowling cited as possible reasons for the failure.
