Whats the point of Hayden Christensen being back for this?
You don't see his face, or even hear his voice, he's fully covered up in Vader's suit and James Earl Jones is the voice, he's essentially a stuntman. And the brief glimpse you did see of his face in the water without the mask it was so covered up in prosthetics it could've been anyone.
Just feels kinda pointless for him to be in this.
