Years ago a friend did a run for a series, It was with Robbie Coltrane on aseries about trains, planes and cars
Or something like that and it was the only a few seconds but it was in the opening credits so it was shown on all the episodes.Anyhow he had a great time, up to Loch Lomond and they were to sail or fly their models.
The plan was to do it and I think they got £100 plus a buffet lunch.
So He had a typhoon submarine 1:100 scale dynamic diver so they asked him to sail it towards the camera diving as it went. The cameraman couldn't get the shot couldn't get the shot as he had to stop to not hit the camera. So they asked him to sail it again and RAM the camera stand as it went under!
After some discussions they offered him an obscene amount of money and he gladly accepted and duly rammed the camera broke it but there was no damage to his submarine but he duly walked away with a smile and a large cheque.
Also Robbie Coltrane was there and when they brought out the buffet lunch he sent it back and demanded the guys all got a proper meal so they ended with a full 3 course lunch!!
Neil if you do go ahead and do it, you need to decide are you doing it for money or for a bit of fun and "bragging" rights at the club for an hour or so???
If it's money your on to plums.... If it's the other then go and enjoy it and have a laugh and see what it takes to get 2/3 minutes of your model on the TV
