Hayden Christensen, who played Anakin Skywalker/Darth Vader in the prequels, is already set to reprise his role in next year's Obi-Wan Kenobi show with Ewan McGregor. But aside from that, there are rumours that he will also be reprising his role in the upcoming Disney+ series Ahsoka. It won't be much of a surprise to see him there, given that Ahsoka Tano was Anakin Skywalker's padawan. What isn't clear is how he'll fit into the story.
Ahsoka takes place five years after the events in Return of the Jedi, but Vader dies in that film, so we're wondering how he'll fit into the story. Perhaps as a flashback or a Force ghost? Rosario Dawson will be reprising her role as Ahsoka, which she played in The Mandalorian. Dave Filoni will write the story and serve as an executive producer alongside Jon Favreau. The series will kick off production in 2022.
