Though Hayden Christensen didn't play Vader in Rogue One: A Star Wars Story, he'll always be the man who played Anakin Skywalker in the prequel trilogy. Christensen hasn't been in a Star Wars project since Revenge of the Sith, but he has been confirmed for a panel appearance in Star Wars Celebration.
Christensen's appearance was announced alongside a bunch of other panel members that would be coming to the Celebration in Orlando later this month. Aside from Christensen, fans will also get to see Peter Mayhew (Chewbacca), Billy Dee Williams (Lando Calrissian), Mark Hamill (Luke Skywalker), Anthony Daniels (C-3PO), Ian McDiarmid (Emperor Palpatine), and Warwick Davis (Wicket the ewok, and other small creatures).
Lucasfilm president Kathleen Kennedy will also be present in the panel, as well as Star Wars Rebels showrunner Dave Filoni. With all these appearances in mind, Star Wars Celebration is sure to showcase a lot of big reveals — for The Last Jedi, and other Star Wars spin-off material.
Going back to Christensen, however, some fans have speculated that his involvement with the panel could have something to do with him working on a Darth Vader solo movie. Rumors had popped up of Christensen playing Vader in Rogue One, but he obviously didn't make a return.
Say what you will about Christensen, but I don't entirely blame him for all the flak he received for the prequels. Part of that was honestly just George Lucas' way of doing things. People who've looked behind-the-scenes have known for a while that Lucas has a problem when it comes to directing actors to do what he wants — even during the first Star Wars.
I'd be happy to see Christensen return for another Star Wars, and I would like to see a movie delving into Vader's life in his prime. Hopefully they lift it off of the Darth Vader and the Ghost Prison comic. That story was absolutely phenomenal.
Star Wars Celebration takes place from April 13–16.
