Quando As Duas Torres chegar ao cinemas em dezembro 50 mil seres virtuais vão sair no tapa na Batalha de Helm’s Deep.

Quem vai cuidar de tudo é o software Massive, da WETA, empresa de efeitos especiais (não necessariamente digitais) especialmente criada por Peter Jackson para a produção da trilogia O Senhor dos Anéis.

When Orc meets elf in digital battle, neither knows exactly what he—or his opponent—is going to do. The elf may swing his sword, but when? His opponent will see it and duck (or not, and not). The elf jumps forward. The Orc cowers—and this time, the elf’s blow finds bone. While the result of the whole battle is broadly predetermined—there is a plot—individual sequences have what might be called programmed spontaneity. Each movement emerges from the one before it.
