But dig this still from the ad itself.
What's that shining in through the slats, if not sunlight? And you can see other examples of the same anomaly throughout the spot. So maybe we should add crap production values to its list of faults. Or maybe the PMO can't simply command darkness whenever Mr. Harper wants to do a Photo Op.
Or maybe the point of the ad wasn't to show Harper working at night, it was to show that he works all day in his office until night falls without any interruption from kin or colleagues. Which means he has no friends nor family life.
Maybe somebody should give Norm Spector a heads up.
