According to Yahoo UK there is a legal battle brewing over the contract to provide the hundreds of extras for Episode VII which may delay shooting. The article even indicates for what those extras would be needed. I think one we probably assumed, but the other is for a popular non-human species, so don’t click through if you consider that spoiler information. Using extras for these roles instead of using CGI models with jarringly unnatural locomotion is a huge positive. Hopefully this legal battle doesn’t tempt JJ do the darkside of CGI.
