The scenes featuring boar were originally planned to use actual, domesticated animals. Since bringing domesticated boar from continental United States was expensive, and the animals available in Hawaii did not look like wild boar and rarely moved (the script required them to run in most scenes), the producers decided to use computer-generated boar instead, along with reaction shots from the actors and first-person sequences from the animals' point of view.[6] Instead of having a stunt double for Kate climbing the tree to place the antenna, Evangeline Lilly climbed the tree herself.[3] The Australian office that hosts the travel agency was filmed in an empty retail space in downtown Honolulu.[7]
