Disney's Maleficent: Mistress of Evil perfectly set up a continued story for the reimagined villain – so will there ever be a Maleficent 3? Based on the famous Sleeping Beauty tale, the franchise stars Angelina Jolie as the titular character. The original Maleficent premiered in 2014 and introduced the new idea that the old villain and her relationship with Princess Aurora were misunderstood. Then, Maleficent: Mistress of Evil, released in October 2019, explored how the pair's story progressed after King Stefan's death – and the film certainly left the door open for a threequel.
