When one of the chimps gets out of her cage and messes around with chemicals, before the action cuts away to three scientists discussing a hair restoring formula, the large vial into which the ape has been pouring the chemicals is full to the brim.

When Barnaby and Edwina emerge from his office to see that Oxley and the other scientists are behaving like children, a panel in the 'wall' to the right of the door moves, and a gap can be seen in the wall of the set looking into his office.
