When Vader has his hand cut off, at a certain point (I forget where) I remember thinking it looks really obvious that he's got a longer arm to create the illusion of a "stump." Perhaps that could be fixed somehow.
true. i think it's after Vader tosses the Emperor down the thing and he's slumped over breathing hard looking down there. the actor is bending his wrist at that moment totally shatters the illusion. always bugged me
