I had several tasks to perform at various stages of these film's pre-production schedules. The first one was to assist in the creation of the cave sequences used to depict Zion, the home base deep underground. The rest all had to do with special effects explosion sequences where there needed to be many different machine like objects that were required to explode before the camera. These items had to be made of specific materials to give off the effect we needed for the shots. I had to help create those originals that were then molded and then cast from the explode-able material needed for the shot. I also helped to sculpt the giant doorway that led into Zion.
