Mel Gibson? Jews? What could go wrong?
Gibson is clearly stuggling, and perhaps angry, with G-d, and hence his erratic behavior. People like that tend to lash out at Jewish people, for whatever reason, I presume the historical connection.
It doesn't help he was raised in a splinter group of/from the Roman Catholic Church that is profoundly antisemitic.
FWIW, the books of Macabees are not considered "cannonical" by most Jewish people, either, in that they do not purport to be divinely inspired, although they are basically undisputed historical accounts, cooborated by a number of other historians.
The Macabees are a great lesson on human governance. They started off great, and a generation or so later, degenerated into corruption, greed, isolated leadership apart from the people, and (shock) spending too much.
I think it would be difficult to make an anti-semitic movie out of the first generation, and rather easy to make one out of the later generations.
Be curious what part he will pick, or if he will attempt to span generations.
