To end the, for the lack of a better word, “controversy” over Snoke’s height in the recent weeks, Neal Scanlan have now revealed that Snoke is 7-feet tall, and also “very, very thin.”

Also, the alien that people are speculating might be performed by Simon Pegg, have been revealed to be Unkar Plutt, whom we first heard about a few months ago (in a lego set, I think?).
Some are even theorizing that he might be more than just a one-scene character since he’s clearly seen in both the Kanata’s castle set, while Pegg have also been seen on location in Abu Dhabi. Some think he might be the person in charge of the Millenium Falcon before Finn & Rey “steal” it while escaping the First Order on Jakku.
