This pretty much sums it up:
In 1996, when the British Broadcasting Corp. aired a short documentary on the same subject, archaeologists challenged the claims. Amos Kloner, the first archaeologist to examine the site, said the idea fails to hold up by archaeological standards but makes for profitable television.
"They just want to get money for it," Kloner said.
Cameron said his critics should withhold comment until they see his film.
"I'm not a theologist. I'm not an archaeologist. I'm a documentary film maker," he said.
Just another film maker trying to make money by making a controversial documentary. Nothing new here.
