Continuity mistake: In the scene where Rube shakes hands with the animal protesters, he is not wearing the trash bag while shaking their hands. He is wearing the trash bag immediately before and after.
Plot hole: People who do not have their souls retrieved, before they are killed, will suffer the effects of the death on their soul, eg. the autopsied man has scars and cuts on his soul. So how come the woman who was crushed by a piano (whose soul was only ever retrieved afterwards) is unharmed in soul form?
