Reply #360: Trust me. The orcs are fictional. As are the Urukai.

[1932]

Jackson had a lot of latitude to make them look like whatever he thought would help make his narrative point.

Whatever Tolkein thought of them (which isn't my concern right now), Jackson thought that making the Urukai look like savage rastafarians on a 'roids rage would help his audience understand the narrative. And I think that that is, if not racist, at least, using race in a way that is a little deceptive. After all, some of the most savage things done relating to race and empire and modernization were done in one direction most often, and it wasn't black on white.
