No, I think it was from his appearance in one of those "different ways to end the world" type shows. Sorry I can't be more specific. He was dressed more informally and the cgi behind him showed a roaming black hole as it approached the earth and the afteraffects, where he goes on to make his explanation about the effects it would ultimately have on the surface of the planet and the people as well. Seems as if guys like him and Michio Kaku would make a lecture series entertaining. They both seem to have a sense of showmanship and passion for their material.
