Phil Tippett (who worked on the Tauntauns in The Empire Strikes Back and the Rancor in Return Of The Jedi) has tweeted a picture of what seems to be a brand new Wookiee! Jason and I think that this is indeed a new Wookiee and not Chewbacca (unless Chewbacca shows up in Rogue One looking a bit different). So the true question is, is this Wookiee from Rogue One or Episode VIII?
