Supposedly, this is a redub that the original voice actor of both Mario and Luigi in Hotel Mario, Marc Graue, did of the opening cutscene back in December of 2011. As far as I can tell, there's no way to actually confirm if this was, in fact, Marc Graue.
The voices do sound extremely authentic, but we obviously know that there are very talented amateur voice actors out there. With the world being so politically correct nowadays, I don't necessarily see a professional voice actor agreeing to do something like this. But then again, that could very well be the reason why it's impossible to confirm that it is, or isn't, Marc Graue.
Warning: Very NSFW Language!
