At the end of this almost perfect film, my wife and I were shocked during the (surprise) ending to see the boom-mike hovering over Willis' head as he talks to his wife...then the camera changes angles. "Did we just see that?"... Back to Willis -
"AIIIIEEEE!!! There it is again!!!"
Boom shots are not uncommon in films... but surprising in one so well constructed and critically acclaimed as this one!
