The candle in Beauty and the Beast is actually a character named Lumiere. He is a French candlestick who comes to life when the enchanted rose is first picked. Lumiere is one of the first people (or objects) that Belle meets when she arrives at the castle. He is very hospitable and immediately takes a liking to her.
Lumiere is also one of the main characters in Disney's Beauty and the Beast animated film. He is voiced by actor Jerry Orbach in the original film, and by Robby Benson in its direct-to-video sequel Beauty and the Beast: The Enchanted Christmas. In both films, Lumiere serves as an advisor and confidante to Beast/Prince Adam.
Lumiere has many memorable moments throughout both films, but perhaps his most iconic scene is during Be Our Guest. In this scene, Lumiere welcomes Belle into the castle with an extravagant dinner party complete with singing dishes and dancing cutlery. It's a classic moment from Disney's Beauty and the Beast that always leaves audiences smiling.
