makeyourdeduction pointed out an interesting facial expression of MF in this pic:
It looks as if this could be part of some sort of promo shoot:
(pic by the-gentler-gamster)
But I am very confused by the set decoration!
This is what it looked like on Friday evening, so before they started filming on Saturday:
Can you spot the difference?
There’s a lamp to cover the blue sign left to the door of 221.
And the lamp was still in place when they started filming/rehearsing on Saturday:
And it’s still there in the evening and even lit:
So why the hell did they take the lamp down in the middle of shooting?
And, no, before you get exited (I would though ;-) ), it’s not a clue for a modern-victorian mix. Because the modern “Baker Street” uses a modern lamp to cover the sign.
(And this lamp seems to be set up for the Special as well: you can spot it in the beginning and at the end of the video and in this pic from Sunday)
