Some years ago, we were approached by a film crew to film at the farm. My poor old Uncle had to go out and do old fashioned farming jobs - using his sythe etc. which did not bother him, as he still used it!! I had to walk down the field leading one of the goats, and had to do the take about 10 times in the rain, until it was right. Surprisingly the goat was very well behaved.
Yes, I was amazed at just how many people there were in the field, and having the boom and camera held over you was a bit daunting to begin with. But, the crew were all very nice, and I did not feel they were making us do anything under pressure. But, when we actually saw the finished product, it was only probably two minutes!! All that standing about etc. all day, for two minutes of fame (which actually went out on a childrens educational programme!!!)
I don't think you have anything to loose by just making enquiries about this!!!
