What stood out is that Teller, who has not spoken a single word on stage in his long career with Penn...actually talks in the video. It's done in a clever way, setting it up so that you think he won't again, of course, talk. But he does.
To be clear, Teller has spoken before on film. He's actually acted quite a bit. I first remember seeing him as a series regular in a 1987 TV series about minor league baseball called Long Gone, that starred William Peterson, Virginia Madsen, and Dermot Mulroney. But I've never seen him speak in a magic setting.
In fairness, this isn't their magic act. This is a "master class" teaching. But that's what makes this unique and why it stood out. That aside, it also looks pretty interesting.
