In Disney's 1991 animated Beauty and the Beast, the castle's enchanted servants have been waiting for ten years for the curse to break.
The prologue explains that an enchantress transformed the prince into the Beast and turned his servants into household objects. The curse can end if the Beast learns to love and receives love before the last petal of an enchanted rose falls.
The film's stained-glass opening states that the prince has remained under the enchantment for ten years. This establishes the urgency of the story while showing that the servants have endured the same prolonged transformation.
The number is sometimes confused with the film's undefined age of the Beast or with timelines from other adaptations. Disney's 1991 animated film specifically presents ten years in its opening narration.
