Milking the cash cow for every dollar, Warner Bros. released the first Harry Potter spin-off movie just five years after the conclusion of the original movies. The five-part Fantastic Beasts series is inspired by Rowling's 2001 magical guide book of the same name, and stars Eddie Redmayne, Ezra Miller, and Jude Law. Johnny Depp also starred in the first two movies but has now been replaced by Danish actor Mads Mikkelsen.
With two movies released so far, the series had already grossed a combined total of $1.4 billion (£1bn) – an incredible $1.6 billion (£1.2bn) when adjusted for inflation. Fantastic Beasts and Where to Find Them, the first film in the franchise, performed the best at the box office, with Potterheads eager for their Wizarding World fix after a five-year hiatus. The film grossed an impressive $814 million (£613.5m) in 2016, or $932.8 million (£703m) in today’s money.
The sequel, 2018's Fantastic Beasts: The Crimes of Grindelwald, grossed $654.9 million (£493 million) at the box office, or $718.6 million (£541.5m) in today’s money.
