During the scene where they are interviewing David Ferry in his apartment right before his death, his toupee changes nearly every time the camera angle does. In one shot, his toupee is riding right above his eyebrows, while in the next angle, it's high above his forehead. At no time do we see him adjusting it on screen, so he must have had to ffilm the scene at two different takes and the editors missed it! Oops!
