OK, we (Mrs. T) and I went and saw KNOWING. All and all it was pretty decent. I actually rather liked it, but I tend to like these kind of movies, so perhaps I'm a bit biased. The story does a complete tailspin toward the end though, but even with that, I'd still rate it pretty highly.
I did, however, notice a few inaccuracies that are kinda nit-picky, but still pretty funny.
One was, on the chalkboard near the beginning of the film, the phrase:
The quick brown fox jumped over the lazy dog
It's a phrase meant to teach children how to write each letter in the alphabet, in cursive script in this particular case. However, the phrase "The quick brown fox jumped over the lazy dog" doesn't contain the letter 's'. It's supposed to be "The quick brown fox jump[s] over the lazy dog"...idiot!
The second thing, Mrs. T pointed out to me, was this. First a little background...the thrust of the movie takes place around present day (just a bit in the future)...October 2009. Nick Cage had a telescope pointed at Saturn and asked his kid to come look at the rings of Saturn. However, the rings of Saturn are barely visible now (and will be even less so in October) since the rings are tilting toward Earth...they will be perfectly edge-on in September (http://www.universetoday.com/2008/03/18/why-are-saturns-rings-disappearing/
Anyhow, I do recommend this movie, even keeping in mind there is a bit of a letdown near the end.
