Run away! Run away!

When Weta Digital, the special effects house who worked on Peter Jackson's Lord of the Rings were putting together the fight sequences for the Helms Deep sequence of The Two Towers using a system called Massive to simulate the fight sequences, they inadvertantly created far too few human characters to orcs. They were amazed to find as they watched the sequence being generated that when the little fake humans reached the little fake orcs and the monsters turned to attack, the solidiers were taken by surprised and ran away in great numbers with only a few standing their ground. Luckily they appear to be a bit braver in the finished film.
