Factual error: In the "No One's Great as Gaston" song (in the tavern) Gaston uses his blunderbuss to shoot three holes (three separate shots) in a barrel of beer. But a blunderbuss is a single-shot weapon. He would have to shoot, reload, shoot, reload, and shoot. (00:27:40)
Factual error: After Gaston stabs the Beast in the fight sequence, there is no blood shown on the knife. [This is a longstanding Disney animation tradition. The House of Mouse seems to believe that onscreen violence is less traumatic if all evidence of it disappears quickly. Thus, you rarely see blood and when it IS seen it's usually minor, even if the wound isn't minor.] (01:16:15)
Continuity mistake: In the 'Gaston' song sequence, near the end, Gaston is sitting in his huge antler chair with Lefou. In the wide shot, there is a bear rug behind the chair. The camera does a close up of Gaston, then in the next wide shot, the chair is on top of the bear rug. Also, after this, Gaston gets up off of the chair and in the next shot, both the chair and the rug disappear completely. (00:29:20)
Trivia: Though not revealed in the movie, the Prince's name is Adam. At the New Orleans Disneyworld, the Princess hotel rooms have portraits of each Disney prince. The 'Beauty & the Beast' prince is shown in human form and his name stated underneath as 'Prince Adam.' In addition, the officially licensed Disney Fisherprice 'Little People' sets include 'Belle and Prince Adam.'
