Have you completed a survey in a theater or mall? I got the call too and called them back. The company is Entertainment works and they are out of California. I was at the movies last week and there was a kiosk set up for Neilsen research with some touch screens. They were asking opinions about Movie trailers that haven't come out yet and what I thought about it, if I would see it, what I had seen, etc. They are just doing a quality control check to make sure that they aren't getting bogus results back from the kids manning the station. It took 30 secs to answer her questions. But they could have left a message.
