So did they replace the force ghost shot? It seems obvious that they did dying Vader from your comments but to what prowse voice too? so Is it safe to assume they dressed him up for the force ghost swap also?
Just the mask scene, no ghost scenes lol 😄 … About the voice, sure it was him. Now the actor has around 80 years old and it’s voice it’s very similar to the voice of James Earl Jones back then. Also they used another actor to do the role of Luke, maybe with this actor his voice was dubed.
