Movie Go!

Yesterday I noticed that the car park at the church halls were pack with cars and large vans and trucks associated with a film company.  A security man was patrolling the car park so I asked him what was happening.  Apparently a film crew had descended on the village to film for the Channel 4 Dalgliesh crime drama television series, although there was no filming on site that I could see.  I visited again today, there was less activity but their presence was still there.  Has anyone heard of Movie Go film and TV facilities?
