I was at that panel and when I saw the first glimpses of the Master, I screamed so loud, I nearly lost my voice. DT made them play the clip after the first time because he felt there was a lot going on, and we need to see it again. Also, the voiceover in the beginning is Timothy Dalton.
I will be posting pics soon - mostly Being Human, Torchwood, Doctor Who and Mighty Boosh. I did take pics of Neil Gaiman but they came out so horribly blurry I had to delete them.
