Chewie was definitely not CGI. His fur around his eyes is smoother and shinier for whatever reason. This is something people have been freaking out and doomsdaying about since the teaser in April. Aside from him looking slightly different, I didn’t think he looked like a CG character. In fact, when he was running around setting explosives, I thought he looked very much like a ‘walking carpet’, and about how absurdly out of place he would look in this modern film if we didn’t know the character already.
