If you just want the Anakin question answered, do not read beyond this first section of this article.
The most common question I am asked every time I mention Star Wars: The Rise of Skywalker has to do with Anakin Skywalker. Will Anakin show up in Star Wars: The Rise of Skywalker?
A few sources have now seen the film and while they were tight lipped in general about what they saw, they did finally give me some confirming nods about Anakin and his involvement in the film.
Other trusted sources have heard the sound mix of The Rise of Skywalker which back up what those who saw the film believe they have heard.
If you have been following spoilers for the Episode IX, this will be somewhat obvious to you. But a pretty general confirmation might make some fans able to relax a little, so I'm sharing that for those spoiler fans (like myself). Anakin's voice is heard at the end of the film and sources say it sounds like Hayden Christensen (rather than The Clone Wars’ voice actor Matt Lanter).
While sound mix tweaks are possible, none of my sources believe the Skywalker voices will be omitted from the climax of the film. Just for the purpose of full disclosure, these viewings are VERY recent but what day the film was "locked" is still in question but we have no reason to believe this has or will change. So there's a slight chance the list of names below could shift in a minor way but we don’t think that is likely.
To be extra clear these are not force ghosts but disembodied voices heard during the climax of The Rise of Skywalker. I'm sure it will make some fans annoyed because it might not be enough for them and they would prefer it to visually happen. Without having seen the film, I can only guess about the efficacy of this inclusion being entirely aural. To the best of my knowledge, you do not see these characters and because some might be living and some might be dead, it makes sense to keep it contained to audio and to show that Rey is doing the important action at the end that matters the most, using defense as her offense as a Jedi should.
One last thing: Please don't shoot the messenger. I'm only relaying what I have been told.
