Doppelganger (1993)

Patrick has a pet cat, Nathan, who is seen in a few scenes lying around the house, eating and being petted. One evening Patrick is investigating a noise from an adjacent apartment, only to find Nathan hanging by his neck on the ceiling lamp cord, dead. For this scene a fake cat with stage blood applied to it’s fur was used. In the apartment complex where Patrick and Holly live, one of the residents has an aviary that houses several pigeons. In one scene Holly’s Doppelganger takes control and a terrible wind picks up. The aviary starts to shake and the birds flap their wings. The birds had reacted to two of the bird handlers slightly rocking the cage back and forth. These pigeons are also seen in two other scenes being fed and as background in their aviary. Pigeons are also seen in a few scenes as atmosphere, sitting on window ledges and flying through the sky in the background. There is one scene in which there is a close-up shot of a dead worm with ants crawling over it. For this, a Gummi-worm (candy) was placed on the ground and ants were allowed to crawl over it. A dog being walked on a leash is also seen in one scene.
