We haven't had the chance to post the locations for the finale yet, but one observation is that some of the locations may be in Hollywood. As far as we know, there is no airline interior soundstage in Hawaii (unless one was jury-rigged), which means the opening scene was filmed in LA as were Lost's pre-crash Flight 815 interior scenes in previous episodes. This places Matthew Fox in LA so that some of his other scenes might also have been filmed there, for example the almost-suicide bridge with its girders doesn't ring a bell on O'ahu. Unless it's some obscure waterfront structure, it might very well be in LA because the view of the lights on the horizon are refracted realistically through his automobile windows, so the far background seemed to be genuine, and not CG. And for a stretch, Walt's closeup might have been filmed in LA too (saves him a plane trip), because it really looked odd and artificial, and why not show the greenery behind him as they did last episode when Ben was standing in the exact same location at the edge of the pit?
UPDATE: We have two sources placing the bridge at Whittier Blvd in Los Angeles as it becomes East 6th St. Thank you to LVT contributor 'Mike Nelson', who even matched some of the graffiti to satellite photos. Here's the
Google Maps link. DocArzt of
thetailsection also pointed out the you can watch news report as Jack comes into the waiting room at the hospital: the tag line truthfully enough reads: "Action 8 News: Crash last night on the 6th Street Bridge".
