It's not a movie but two or three nights ago I was flipping through the channels and came across HBO's "Big Love". I don't follow the show but happened on it during a scene in which a man was getting a str8 shave by a woman. It was obvious they didn't have a clue. The woman held the blade with the scales completely opened rather than at right angles to the blade and not held between the fingers. The blade was at the wrong angle to his neck and he was sitting upright rather than leaned back. And no skin stretching, either. They probably ground down the edge to keep anybody from being killed.
