‘The Twilight Saga: Eclipse’ – Summit Ent.
As you probably noticed upon first seeing The Twilight Saga: Eclipse, the film’s werewolves differed quite a bit from the way that they were presented in The Twilight Saga: New Moon, and Phil Tippett – the man responsible for the CGI wolves – has explained exactly why that is to MTV.
With the New Moon wolves, he explained, the idea was to get a group of “heroic sentries” so that “[w]hen the wolves met the humans, we attempted to make it appear as though the wolves had a center of conscience that was definitely human.”
For the Eclipse wolves, though, “David [Slade] really wanted to play it that the wolves were far more primordial and much more wolflike. The wolves became less sentries sent from God and a lot more twitchy, uncertain, fairer animals.”
This probably has something to do with the overall schema of the action at hand in Eclipse. In New Moon, the wolves had their fair share of vampire-hunting fun, but with Eclipse, they’re right there in the thick of the conflict.
Still, Tippett and his crew had to make sure that Taylor Lautner’s “Jacob” wolf brought that human-esque emotion to the fore. “Through non-language pantomime on the wolf’s part, he had to appear to be engaged and try to make his expressions telegraph the tragic love that is their relationship,” he explained.
All this and a lot more about the CGI in Eclipse was explained by Tippett in MTV’s feature, so you’ll definitely want to head over and read up on how the CGI work was done in Eclipse here.
