Series 10 Filming & Behind the Scenes

[Forever Secret]

Didn't really trust the Manchester thing, Why would they be Filming in Manchester?, Usually it would seem no matter where the episode is set its mostly and nearly always shot in and around London... unless there's some kind of landmark or setting they need for a reason that suits the episode.
Think the only time they moved was to film in Moscow for some of S7 and for S8 where they filmed in Majorca for the scenes set in Cyprus, can't remember any other time they've not filmed in or around London

I wish people would post pictures when they see filming, then more speculation can begin haha
