Both the BBC and BBC America posted a number of videos just prior to and after the broadcast of "The Day of the Doctor". It seemed a bit silly to post them all individually so here is your "two stop shop" for "The Day of the Doctor" video goodies.
Let's start with the good old BBC:
1. Happy Anniversary from Matt Smith:
2. Happy Anniversary from Steven Moffat:
3. Tardis Index File: Zygons:
4. "The Day of the Doctor" - deleted scene:
5. Behind the Lens - the Making of "The Day of the Doctor":
6. The Five-ish Doctors (reboot) - you really MUST watch this. A totally brilliant video where the Classic Doctors try to get involved with the Anniversary special:
Screencaps from most of the above will, of course, be forthcoming over the next few days. Shortly, we'll post the BBC America version...
