Did you know that the skybox (background image) of Wet-Dry World in Super Mario 64 is an altered photograph of a real-world city? It was originally believed to be Casares, Spain, though the actual location has since reportedly been confirmed as Shibam, Yemen. Another interesting tidbit concerning Super Mario 64 is that Mario's original voice in the 1995 beta version of the game was archivally provided by the late Mel Blanc via the Warner Bros. Sound Effects Library. Pretty cool, huh?
