In the 2014 film "Maleficent," Maleficent's kiss breaks the curse and awakens Aurora.
The moment deliberately reverses the familiar ending of Disney's 1959 animated film "Sleeping Beauty," in which Prince Phillip's kiss awakens the princess. In the live-action film, Phillip attempts to kiss Aurora but nothing happens because their relationship has not developed into true love. Maleficent then kisses Aurora on the forehead, and Aurora wakes.
The scene completes Maleficent's emotional transformation. She originally curses Aurora after being betrayed by Stefan, Aurora's father, but gradually becomes protective of the child. By the time Aurora falls into enchanted sleep on her sixteenth birthday, Maleficent genuinely loves her in a maternal way. That bond—not a conventional romantic romance—is what the film presents as true love.
The most common mix-up is answering Prince Phillip because that is the conclusion of the animated classic and the traditional fairy tale. The 2014 movie is specifically a reinterpretation told from Maleficent's perspective, so its awakening scene intentionally changes the answer.
