Continuity mistake: During Braniac's attack on Metropolis, a few of his drones get inside the Daily Planet and attempt to go after Lois, Jimmy, and the other guy. They quickly shut the door and prop a file cabinet against it as a barricade. The one they push against the door has just two solid drawers on it. There are two more files cabinets with 6 drawers each next to the wall. Moments later, it is shown that there are now only 2 cabinets in the room, and the two 6 drawer ones are at the door. The 2 drawer one has vanished. It also shows the window blinds going from broken to fixed.
