Once again it appears to be light out when it should be at night. When the cars pull up to Inspector Henderson the head lights are on even though it's quite light out (as it is when Jimmy and Lois leave) but when Perry is shown close up talking to Inspector Henderson it's pitch black out.
When alone in the assistant's room, Kent (Superman) searches all the drawers and shuffles the contents. This seems unnecessary for someone who has x-ray vision and only has to look.
