Doctor Who 50th Anniversary Special 2013: Clara and The Doctor are shown something 'not possible' in exclusive sneak peek video clip at 'Day of the Doctor'

Did you forget that one of the biggest moments in the history of Doctor Who is happening this month? How dare you! Well, assuming you actually didn't forget (like a good Whovian), we have some updates for you. So here is the brand new sneak peek, special video clip from the 50^th anniversary special The Day of the Doctor.

In this clip we see Clara (Jenna-Louise Coleman) and the Doctor (Matt Smith) viewing a large painting. What they see, however, can't be possible according to Clara's immediate response to it. What do you think they're looking at and what do you think it means for the anniversary special?

Whatever this painting is, we know we're in for quite an experience with the upcoming episode. David Tennant and Billie Piper reprise their roles in this special alongside John Hurt as a mysterious Doctor regeneration that brought shame to the name. What did he do to be so hidden in the Doctor's mind and what makes him come out?

For this special, Doctor Who and the BBC have organized a special promotional website for exclusive clips and contests for the episode. This has made this upcoming special into more of an experience for fans of Doctor Who. Check out more at DoctorWhoSaveTheDay.com and be ahead of the game in terms of finding out everything you possibly can about the upcoming 50^th anniversary special.
