You can win what are sometimes worthwhile prizes by giving the closest prediction to what certain movies earn in the US during their opening weekends. Some of the prizes, though, have been turkeys. I know because I have won some of these contests.
The contest coming up is for two people who get the closest estimations-- both over and under-- to how much
The Avengers will make next weekend. Predictions have to be in by 10:00 PST on May 4, 2012.
I cannot remember anyone ever predicting the exact amount some movie made over a weekend even though someone did come within $40,000 or so.
