In the opening scene and through, you see a North Carolina tag in the front of the Grand Prix as it parks. License plates in NC are only required in the back of the car and are in the format of ABC-1234 and not as shown. Also the month and year the tag expires are in the upper left hand and right hand corners of the plate.
Tobacco beetles are much smaller than the insects shown, about 2-3 mm long.
The plants in Dr. Voss' lab are not tobacco plants. They are Peace Lilies with the white blooms removed.
At about the 43-minute mark when Skinner visits the Morley Tobacco Agricultural Research Division, the caption at the bottom left of the screen says "MORELY TOBACCO".
