If I were rich and money were no object, I would produce a TV special debunking the 2012 nonsense. The working title is 2012 Is Not The End! It would be an hour for sure, two hours if possible. There would be plenty of computer animations and hands-on demonstrations illustrating how 2012 theories can't work.
I would invite knowledgable experts to show, in explicit detail, how each and every 2012 scenario is wrong. The list would include, but not be limited to:
Our own beloved Astrogeek, Bill Hudson
Phil Plait
Michio Kaku
Neil Tyson
Brian Cox
Jay Windley (JayUtah over at the Bad Astronomy forum and webmaster of Clavius Moon Base. He's best known for eviscerating the Moon Hoax, but I think he'd definitely have wise words of saged counsel on the 2012 garbage)
My first choice to narrate and/or host the show would be David Tennant. Next on my list would be Sam Neill.
Any excess profits would be donated to the National Science Foundation or a similar organization, to help educate our children so that they are less inclined to believe in fantasies such as those the 2012 proponents live in.
