According to Pfann's reading, the ossuary did not house the bones of "Mary the teacher," but rather of two women, "Mary and Martha."
"In view of the above, there is no longer any reason to be tempted to link this ossuary ... to Mary Magdalene or any other person in biblical, non-biblical or church tradition," Pfann wrote.
In the interest of telling a good story, Pfann said, the documentary engaged in some "fudging" of the facts.
"James Cameron is a great guru of science fiction, and he's taking it to a new level with Simcha Jacobovici. You take a little bit of science, spin a good yarn out of it and you get another 'Terminator' or 'Life of Brian,'" said Pfann, who briefly appeared as an ossuary expert in the documentary.
In Israel on Tuesday for a screening of the film, the Toronto-based Jacobovici welcomed Pfann's criticism, saying "every inscription should be re-examined."
But Jacobovici said scholars who researched the ossuary in the past agreed with the film's reading. "Anyone who looks at it can see that the script was written by the same hand," he added.
Jacobovici has faced criticism much tougher than Pfann's academic critique. The film has been termed "archaeo-porn," and Jacobovici has been accused of "pimping the Bible."
Jacobovici attributes most of the criticism to scholars' discomfort with journalists "casting light into their ossuary monopoly."
"What we're doing is democratizing this knowledge, and this is driving some people crazy," he said.
