Steven Moffat at yesterdays filming

Someone else was at yesterdays filming who we didn`t know about.




Yes, Steven Moffat himself was there to see his era begin.

Also, I`ve found a theory on the internet about the filming yesterday.
What if the Sea Devils are back?
They`re filming on a beach after all.
Some believe that this is true and that the metal junk is a crashed spaceship.
What do you think?
