If you got a call from Nielsen Movieview, it's just a movie study about the movies that are out or will be opening in theaters soon. They're not trying to kill you, or use your information for frauds or nothing like that, it's just a 5 to 10 minute survey. If you don't want to do it just say so, there's a disposition screen to follow whenever the household that's been called isn't interested in the study. Don't scream, throw the phone or do dumb things like that, that won't help you a bit, you'll probably get a call back sooner that it would normally occur if you do so since the person was annoyed by your rudeness.
Even if I had an interest or the time for a movie survey, I wouldn't give them the time of day...EVER! How rude to be calling at almost 9:30 on a Saturday night.
