Is Hayden Christensen back in The Last Jedi?
He was seen at the Pinewood Studios, where “The Last Jedi’s” shooting is happening. Could this mean he'll appear, like in the form of a Force ghost? I personally hope so, not like many other hardcore fans, I enjoyed AoC and RoS, especially RoS...

It would be interesting to see what they would do to put him into the film. I imagine it would be a ghost situation since the character died. But you never know. They could go the rebirth of Christ angle instead.
