Maggots As the women are driving down the road, Christina reaches into the back seat and opens a foil wrapper with some old leftovers that are crawling with maggots. She throws it out the window only to have it smash against the windshield of the car and splatter all over the glas s. The maggots were computer generated. Horses A horse-drawn carriage crosses the street as a woman parks her car. San Francisco company Waterfront Carriages supplied the horse-drawn carriage. The owner of the company doubled as the driver for this scene.
