You're probably right about there being more Klingon speakers than Aramaic speakers, and certainly there are FAR more Latin speakers, since studying Latin is still not uncommon. I'm sure the objections you raise have been made to Mel, but since he is financing the project, he can do what he wants. I'm not totally clear on his motivations, but have read that he did it to be as accurate as possible. That seems a bit odd to me, unless they have some early copies of the Gospels written in Aramaic. I think that he might have thought the film would be less controversial that way, since few could parse the words. If so, that didn't work. The point has been made, though, that most who see it will know the story well anyway. I'll go on the record as saying that it should have subtitles.
