I know many of you like the change in ROTJ to have Hayden show up as a the ghost-Anakin at the end (seeing my personal pic, you can tell what I think ). However, Lucas goofed when he did this scene. I just noticed it today while watching ROTJ (its been an OT DVD weekend for me, watched the whole trilogy). Most of us (mostly likely all of us) know what outfits Anakin wore during the prequels. Well, look at him as a ghost in ROTJ again, because he isn't wearing anything that he wore in those prequels (aside from the robe). In the ROTJ ghost scene, he has a brown robe, long light tan tabards, long light tan tunic, light tan pants, and brown under shirt. Basically he has the same outfit as Obi-Wan in the OT.
Now remember, the arguement to have Hayden play the part is because this is the last "look" or "version" of Anakin before he turned to the darkside (because some people think thats the only way you would look when giving in to the force and becoming a "ghost"). However, its still not correct, as we all know that Anakin's look before turning to the darkside was in a dark brown robe, regular sized dark brown leather tabards, regular sized dark brown tunic, brown pants, and black under shirt. Good job Lucas, you screwed up that change too.
And to debunk any arguements that it was a previous outfit he wore, look again. Anakin never wore an outfit, such as he did as a ghost in ROTJ, in the prequels, ever. So like I said, Lucas goofed on his own change to the OT.
