Okay, this was a bit spooky...
There's a new movie called "Beowulf" coming out that is being done in computer graphic "live action," and I've been following the progress.
A "restricted" trailer showed up that required you to fill out your name, zip code, and date of birth to prove your age.
Typically, I throw such things a fake, and they eat it. This site didn't. After two tries, just for the hell of it, I threw in my real data. It paused for a while, then moved me into the site.
Question: what did they check this information against?? And how?
