a picture from Vanity Fair that Andy Serkis is playing an all CGI character called "Supreme Leader Snoke".
I guess because Snake just seemed to on the nose (and Snape was already taken). Yep that is all. What is he leader of? No info. What does he look like? Remains in the cone of silence until a toy leak tells us. On the bright side Snoke will be partially created by the world's acting expert on motion capture so at least we know he will be interesting to watch regardless of how likely Abrams screws up the character itself (Abrams is extremely weak when it comes to characterizing bad guys). So until next time when the interwebs report with breathless abandon on what the character looks like.
