The first trailer for Disney’s The Lion King prequel, Mufasa, has revealed some important details about the movie’s story, but also retconned one of the original movie’s most poignant and important scenes. After the character’s original appearance in the 1994 animated movie and the live-action remake, Mufasa will offer an in-depth look at the legendary lion’s rise to power establishing the dynasty that eventually leads to Simba. However, while this story will be compelling for long-term fans of the series, several key details don’t sit neatly with the established narrative.
