Sherlock series 3 filming outside St Barts hospital, London

April 14th, 2013. Having seen them filming yesterday, I went back to London today with my friend and spent a long time watching them film. I managed to get some footage of several scenes they were shooting, and I have to warn you that they do contain small spoilers of a sort don t watch if you re sensitive to any sort of new material from the set. I ll be posting another video soon, with behindthescenes footage I shot of different actors, and footage of the crew prepping the set.
