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.
Though not revealed in the movie, in the New Orleans Disneyworld Princess hotel rooms there are portraits of each Disney prince. The 'Beauty & the Beast' prince is in human form and his name states underneath 'Prince Adam.' Also the officially licensed Disney Fisherprice 'Little People' have a set which contains 'Belle and Prince Adam.'
