Seems the BBC are very keen to bang the drum on making sure we abide by the government's current lockdown rules, even if its to the detriment of ordinary people's livelihoods and mental health.
And yet, this video purports to show the BBC filming an episode of Doctor Who on a beach in Wales these last few days, and there doesn't appear to be much SD or mask wearing going on.
The commentator in the video does make the point that such filming for TV shows is "exempt" from Covid rules (1m13s). I don't know if that is true, but one does wonder why?
