Hayden Christensen may reprise his role as Darth Vader and/or Anakin Skywalker in Star Wars: Episode VIII, directed by Rian Johnson, if this news tidbit is to be believed!
Making Star Wars was told that: “a team in the U.K. are soon heading to the U.S. to begin training Hayden Christensen for a Star Wars: Episode VIII appearance of some sort.”
There's been much conjecture regarding what role, if any, Anakin Skywalker might play in Disney's new trilogy. This follows the second teaser trailer for The Force Awakens in which Luke describes his father as having the force in the current tense. A force ghost a la Obi-Wan Kenobi in the original trilogy? Maybe.
Gareth Edwards' Rogue One is set prior to the events in A New Hope and there's no reason not to envisage Darth Vader making a cameo in the first Star Wars Anthology film, too. An alleged on set sighting of Darth Vader's helmet and working chest piece has only fuelled more rumours. The character has most recently appeared in the brilliant Star Wars Rebels on Disney XD and in Marvel comics.
Either way. Looks like the Dark Lord of the Sith is set to return to a multiplex theatre near you.
