Ugh! Sorry about the typos in the last werewolf question. Here is another one. The mutated wolf (to me at least) most resembles the classic wolfman (ie Boris Karloff). Basically a large man with lupine feature, but still mostly a man. However, at one point duirng the battle in the Upgrade his jaws jut out like a dogs and the ears gown more pronounced, more wolflike. Here he was more akin to the modern Werewolves like those shown in The Howling series. Does he actually grow more physically wolflike here (ie "When Wolf becomes angry or outraged, a startling metamorphisis occurs.
The other alternative is that this is just a visual device (imagery) that signifies his rage. No actual transformation takes place. Which did you intend. Either way it is a neat effect.
