Two scenes shot on LAX's mosaic-backed moving walkway, years apart: Pam Grier in the intro credits of Jackie Brown, and Jon Hamm as Don Draper in last night's season opener of Mad Men. Compare The Graduate.
Matt Haughey carefully spliced stills from the two scenes together to create this exquisite composite. It's unsettling, yet intriguing, to see the two stars with their impassive public don't-bother-me faces appearing to stand before one another. The walkway hidden from view, it could be anywhere in abstract LAXspace.
But I prefer an alternate explanation, where the context of the automatic walkway is assumed: Don has turned around in order to travel backwards while chatting up Jackie, but Jackie is having none of his bullshit.
(For context, here's video of the mosaic and walkway.)
