  Moore's transformation into "Gollum" was more extensive, with layers of silicone prosthetics glued directly onto her body. Red and blue wool was embedded in the silicone to mimic the appearance of veins beneath the skin. Persin used silicone because it looked more natural and did not easily wrinkle during the filming of action scenes. When Elisabeth runs down the hallway, Moore was switched out for a thinner body double to match the idea of Gollum having a "spider-like" physicality.
  
  A sophisticated fake head, capable of realistic bleeding, was created for the mirror-smashing scene. Qualley smashed the fake head against the mirror and Moore mimed the action later with her real head; the visual effects team seamlessly blended the two shots to depict the head-on-mirror impact and Moore's reaction.
