Goofs

The "HELP" sign drawn on the mirror by Joan is written in skinny, very straight and angular letters, but when it is projected, Batman-style, on the wall outside, the letters are then rounded and fat.

When Martin climbs the utility pole, he is barehanded; however when he grabs and goes down the electric wire, he is clearly wearing thick black gloves. When he crash-lands through a window, he appears to have no gloves but later removes thinner, flesh-colored gloves.

At the end of Chapter: 14 (repeated at the beginning of 15) you can clearly hear the director, Robert F. Hill cuing Luana Walters to begin running. You can hear him say; "Go!" right before she runs to the door.

In Chapter: 1, when Joan, who is wearing an ankle-length skirt, falls sitting on her behind, after trying to climb the fire escape, there is a direct view of her very white underwear. In the next frame, after the cop passes her, she is filmed from the side, averting the unfortunate view.
