We spotted this film crew and scene down on near the river, under London Bridge station. No, we have no confirmation that this has anything to do with Doctor Who - but it is immediately what we thought of.Extras, spooky lighting, extra theming added to the walls? We also spotted a man dressed in brown overalls - and we were pretty sure he wasn't just a normal construction worker.
Are we just being hopeful? Is it an advert for flatulence tablets or something?
(And to be honest - the photo doesn't give anything away. But trust me, we saw something going on down there).
