This is what I had read about Andy Serkis' character.
- Andy Serkis’ character basically looks like an old man, zombie like, almost risen from the dead.
- He is being referred to as “Uber”, similarly to how Ridley is being called Kira and Nyong’o is being called Rose.
- “Uber” has communication with Adam Driver’s Sith character, and a character played by Domhnall Gleeson. Serkis potentially is the Master pulling the strings from behind the scenes.
- All three characters are part of the new “Empire” which Gwendoline Christie’s character is also a part of. She is confirmed to be playing a Chrome Trooper.
