When did he admit this?
I believe he modified his position to the film will cause anti-Semitism.
I believe he also said he was still concerned about the portrayal of some of the Jewish characters being shown as urging the crucifixion of Christ.
I saw him admit it on TV. I think it was on O'Reilly's show or maybe it was on Capital Report or Hardball. Upon hearing it, my reaction was gee if you are worried about what anti-semitism actions might result from the film maybe you shouldnt have given it so much publicity. I doubt many would have heard about or had much interest in seeing a violent religious movie that was filmed in aramaic and latin.
