^Great post, Thenamir. I could see it play out crisp and clear in my head and have nothing to add. That would be a great opening scene.
As for the trolls, I agree with the posters who opted for a more humourous approach. Of course, the party are in grave danger and it should show, but if the director can't see the great potential for comedy in having three cockney trolls arguing how to best cook a bunch of dwarves he should pursue a different carreer.
And isn't it a known fact that orcses, football hooligans and other likeminded scum speak English with a cockney accent?
