 CONT: In the model train scene (in the basement of the estate Luthor  inherits), when the model ground splits open it for some reason has  perfectly modeled sides to the crack. If this were a random breakage  in the model you would expect the internal space to be hollow with  just a wooden frame.  When walking to play the piano with Jason, Brutus stops for a moment  so we can see the back of his head, the scene changes to a shot of  Lois then back to Brutus. From just under his cap you can see a bit  of the tattoo on the back of his head, the shot before you couldnt.
