I highly doubt that if they announce it that they would boast all the individual reversions on stage. And they wouldn’t be removing him from the movie anyway. If it’s released, the OUT will be presented as bonus material or an alternate cut. And it’s not like Hayden actually performed in ROTJ. More like George abused his likeness. Didn’t he just swap the heads?
Yeah it was a headswap from a ROTS outtake.
