Re: 50th aniversary special trailer at Comic-Con
Just looked it up on YouTube, (EDIT: and now it's just been posted above) and turns out you are right. It is reaction shots of the cast of The End of Time with narration from Timothy Dalton, and I guess I mixed the shot of Tennant with an explosion behind him from when the Master was attacking him with his Sith lightning attack with the Voyages of the Damned scene. My bad.
