I have....i did a few interviews for a company and also extra work in a commerical. Amazing how many takes....until they get the right shot! We were there for hours ....just to make a 30 second scene.
Yep When I was at secondary school the local news came to the school to do a piece (dunno why) and I walk by and saw it all and was jumping up/down in the background shouting "Hi mom" behind the presenter - when it was broadcast, sure enough their I was as plain as day doing the above. I was actually embarrassed lol
I play in the movie "Thick as Thieves" whit Antonio Banderas and Mordan Freedman. But they show me only for a couple seconds.
