Hayden as Anakin’s ghost. It doesn’t make sense for him to appear as an unscarred Shaw because he never looked like that.
Doesn’t make sense for Jacob Marley to appear in chains because he never looked like that.
Doesn’t make sense for Johnny Bartlett to appear as Death because he never looked like that.
Doesn’t make sense for whoever-the-hell-she-was to appear as whatever-the-hell-this-is because she never looked like that.
Doesn’t make sense for the Maitlands to appear as stretch-faced monsters because they never looked like that.
