The second trailer for The Day of the Doctor will premiere online on Sunday, the day after the release of the initial trailer. The BBC stated:
And to really make this a special weekend we’re also releasing a second trailer on Sunday. Versions of this trailer have been seen at industry events but this is the first time it’s been released in its finished form, complete with the kind of special effects that help make The Day of the Doctor so epic.The trailer seems to be the trailer that was premiered at San Diego Comic Con back in July, with the first trailer being a brand new, never-before-seen trailer.
We'll be posting both trailers as they arrive this weekend (remember, the first trailer airs at 8pm tomorrow).
