Reference Time: Part 3: The Forest Scene Lars von Trier's Antichrist
The footage for this scene feels very comped, things feel slightly "off" but in a good way. In some of the wide shots, she has an almost stop motion feel to her movements. I suspect that this look was achieved by adding green screened footage of her walking into stills of a forest. Fog was probably added with particles. In Fallen, when Sarah enters the forest, bits and pieces of the animated hell she'll fall into begin to appear in the forest. There are a few ways that I can demonstrate this turning point in the story; either with adding paper elements to live footage, or by deconstructing live footage and photography and puppeting/animating the deconstructed elements in a similar way to the animated portion.
