Even though this did make me laugh, I’m really just posting it because it’s a good excuse for a rant explaining why Anakin appears young at the end of the DVD/Blu-Ray edition of Return of the Jedi. It all really springs from this conversation earlier in the movie:
Luke: Ben! Why didn’t you tell me? You told me that Darth Vader betrayed and murdered my father.
Obi-Wan: Your father… was seduced by the Dark Side of the Force. He ceased to be Anakin Skywalker and “became” Darth Vader. When that happened, the good man who was your father was destroyed. So what I told you was true… from a certain point of view.
Lucas has explained that that line is why the Hayden Anakin was added to Return of the Jedi. Anakin “died” when he was young, thus that’s what his Force Ghost looks like. As Sith cannot become ghosts like Jedi, his ghost wouldn’t look like what Vader did under the helmet. And as there was no younger Anakin back in 1983, they just used Sebastian Shaw in Jedi robes as the ghost at the end of the original Return of the Jedi.
