The scene in which Dave starts listing to Hurley why the island events are occurring in his mind suffered from continuous interruption, as military exercises on Joint Base Pearl Harbor-Hickam led to many takes being ruined by plane noises. Weather problems also plagued production, with loud waves causing Hurley's and Libby's beach scene to be redubbed in post-production, and rain on one day changing the location of the basketball game scene to an indoor court, and also leading to a second day of filming on the cliff. The cliff was digitally redesigned in post-production to appear as if the actors were standing on the edge. Dave's jump was done by making a stunt double jump in front of a bluescreen, with the body hitting the water and resulting splash being rendered through computer graphics. The mental hospital was shot at the Laniakea YWCA in Honolulu, except for Dr. Brooks's office, which was done inside a studio.
