They didn't show Borat at my town's theater either last weekend, but they are this weekend. To see it I had to drive half an hour, but it was completely worth it.
I read that it was originally going to be released in 2000 theaters, but three weeks ago a poll found only 20% of people were even aware of this movie. Supposedly they decided to cut the number of showing theaters to 800 expecting it to be a flop, but now they realize they underestimated Borat and missed out on opening weekend of the best comedy in years.
