 The plan behind the scenes was to create an intriguing visual signature . To serve the subtleties of the script and to help personify death , production designer John Willet developed the concept of " skewing " the sets . " What I 've tried to do with the sets themselves , with their design and with various color choices , is to make things just a little unnatural , " Willet explained . " Nothing that calls attention to itself , but instead creates a sense of uneasiness — the unsettling feeling that something 's not quite right " . To achieve this mystique , Willet designed two versions of virtually every set — one version was used before the crash and the other sets were used for scenes after the jet explodes .
