Speaking yesterday at the ICCCon, Palpatine actor Ian McDiarmid hinted that he would play the Sith Lord again in upcoming Star Wars series.
McDiarmid reminded the audience that “certain series” will take place in periods when Palpatine is around, and he added:
“I have nothing to tell you, but who knows? Whether my physical presence will be there or not, my presence will definitely be felt.”
This could refer to Obi-Wan Kenobi, Andor or the second season of Star Wars: The Bad Batch. These three series take place between Episodes III and IV, when the Emperor rules the galaxy with an iron fist.
