The fact that Sherlock is back in production and filming around the UK has drummed up a fan frenzy. Stars Benedict Cumberbatch and Martin Freeman recently shot in Bristol and Cheltenham with photos popping up across the Internet, leading to potential spoilers. Now, as the show heads to London, producer Sue Vertue has sent a plea to Sherlock lovers to let the team get on with its “punishing” schedule and ask that people avoid posting spoilers or daily locations. On the other hand, Sherlock network the BBC yesterday released official videos of the Doctor Who 50th anniversary special shooting in Trafalgar Square. I hear the reasoning for getting in front of Doctor Who was because the shoot was “bang in the center of London” so already very public. But even a well-placed BBC insider says the Sherlock locations are something of a mystery. Click over for Vertue’s note:

As many of you are aware, we’ll soon be embarking on our first London leg of filming for series 3. I’m also aware that there is quite a lot of speculation about where we’re shooting when. I can’t stress how much we the Producers and Benedict, Martin and the rest of the cast appreciate your love and dedication to our show – we’ll endeavour to live up to your expectations for Series 3.

What I am nervous about is that our London shooting schedule is punishing and will really give us very little time to interact with you. The actors really hope you understand that.

Also, and I know this is probably asking a lot, the majority of fans and indeed ourselves would REALLY appreciate it if you didn’t post pictures or spoilers or ideally our daily locations.

Thanks for your understanding. Sue x
