I was actually most affected by Donnie's face through the movie, particularly in one scene where he switches, on camera, from the soulless, leering grin of madness to the alert,
slightly embarassed face when his younger sister walks in on him.
Knowing this, the desginers should have fitted a
slightly less
embarassing horn.This brings us back to the common electric car question, will people get run over because they can't hear them coming?
