I was a main feature in a documentary made a few years back. Along with a friend of mine and a guy we kind of helped make a bit (in)famous.
I had hours of footage of me filmed, interviews and so on, but at the end decided I wanted no part of it and asked them to remove me from the finished product. I can now only been seen in it for about 10 seconds tops, as my friend and I were both instrumental in this thing and the maker felt he needed to include me somewhere
I have never seen the end result, even though its aired on TV in New Zealand and been shown at film festivals round the world.
TBH you end up saying things, being normal and then thinking you've made a total arse of yourself and worry you'll come over like a git. And the camera adds about a stone in weight to you.
I didn't get paid a penny for it, so it wasn't about that, or being famous for 5 minutes, it was a special time in my life and at the time I was happy to share, but afterwards I just wanted to be left alone. Once its out there, you can't take it back. And you have to sign a release form before hand so they can pretty much use what they want once filmed. Luckily I was the only one involved who never signed one
