See a great list of resources at the CounterCult blog.
Here is a Fox News video - not the greatest response from the Christian Skeptic side, but that is no surprise - when will they ask somebody like James White to be the counterpoint to this effluvia?
“We are also seeing the danger of investing Hollywood celebrities with nigh unto divine powers. James Cameron brought us Terminator and Titanic, but now he seems to have become an archaeologist and theologian as well. He is quoted as saying, “It doesn’t get bigger than this. We’ve done our homework; we’ve made the case; and now it’s time for the debate to begin.” Well, if a true scholarly debate is what they wanted, they would have presented this material first in a completely different context. They don’t want debate anymore than Dan Brown did. They want money, they want power, and evidently, they know the best way to get it these days is to join the “attack Christianity” bandwagon. They have presented their conclusions before the debate itself, and that is so that they can poison the well. When the debate finally begins, the money will already be in their pockets, the damage done, and for the foreseeable future we will be dealing with people repeating their claims as established facts.”
Here is practically the entire documentary on YouTube - Dr. White - I know you do audio responses, but maybe now is the time to branch out into video?
(Just thinking...a cool format would be to do a "response position" to the off center, right side of the screen shot, by doing a left profile, off center interview type shot. Hey, August - do you have a digital video camera :D )
