Where DID you buy the basing kit for the Ent??
And yes, the film had it completely wrong about the banners - Aragorn unfolding the black banner on Pelennor Fields was the main instigation of the returning heir to claim the throne.
The scene in the extended DVD with Boromir shouting after retaking Osgiliath was about right, though... I just don't think the tree was silver..??
I think the flag was a little more cream colored so the silver would stand out better. I just saw the movie again a couple of weeks ago but I didn't pay attention to the flag. Anyway, I agree that black and silver looks so much better on the playing field. And so I'm cool with that.
Sure, it's your game and your minis

I was just referring to the original text as compared to what was seen on screen. The black banners look better with the black/silver livery of Gondor, too.
