non-uniform orcs
 

has anyone noticed that before the battle of helms deep (when the orcs start beating the ground) most of the orcs aren't pounding together, but they still sound as if they were pounding in uniform? i mean, the first orc to get shot pounds his chest WAY off beat.

Yeah! They were marching towards Helm's Deep too, and if you watch only a couple of orcs are really marching in time. I guess the ppl in that New Zealand stadium had better timing than the Uruk-Hai army.

Yeah, I noticed that too. Stupid Orcs aren't coordinated to do anything, let alone take Helm's Deep.
