The Borat flick dominated this weekend, taking in US$26.4 million at the box office, according to the AP story on CTV.ca.
In talking to a few folks, it seems the crowds were definitely weighted to the 24-and-under set, and there's a strong possibility the last movie they saw was Jackass 2. :)
The consensus seems to be funny, yes, but not something people (at least those of us over age 24) would run right out and see a second time.
