Director Chris Weitz has revealed a little tidbit on how the shapeshifting wolfpack will appear when they are in their wolf form!
They will be computer generated about the size of horses but Weitz has revealed that he will have the Actors' eyes digitally pasted to make it look as realistic as possible.
He also notes that the pack have been doing a bit of 'brotherly bonding' in preparation for their roles-
"The Twilight sequel is filming now, and between takes, the actors usually are working out with barbells, doing push-ups or chowing down on steak, Weitz says. “They went through wolf camp together, and they are in constant training. It paid off as a bonding thing for them and helped them to get to know one another. They drove each other to get more buff.”
