Trivia: The giant Kairos ant had a contortionist inside its costume, walking face up on splayed hands and feet. This worked well in rehearsals - on a flat studio floor. On outdoor location, unfortunately, he could neither see nor navigate the terrain, and fell into a ditch, reportedly treating the film crew to some "rather colorful language" in the process.
