Another thing AI could be used for is creating a Force ghost of Anakin who’s actually an older version of Hayden Christensen.

I understand why Lucas replaced Sebastian Shaw with Hayden. He wanted to create a stronger connection between the Prequels and the Original Trilogy. And honestly, I’m all in for it. But including a younger version of Anakin doesn’t make sense from a narrative standpoint. Anakin didn’t die on Mustafar, he died on the Second Death Star, when he turned back to the Light Side and sacrificed himself to save Luke. That’s basically the entire reason Return of the Jedi is called Return of the Jedi to begin with. It’s the return to the Light Side of the fallen Jedi, the return of Anakin. Thus, Anakin’s Force ghost shouldn’t look like his younger self, he should look like his older self.

So I’m all in for having Hayden Christensen in Return of the Jedi, but he should look like a 40-year-old version of Hayden, not a 20-year-old one. AI could fix this by giving us exactly what we need: an older version of Hayden Christensen that we can use instead of the younger version.
