While the gun barrel sequences in James Bond films have not changed a great deal visually, one element that has evolved constantly is the music.
"It's the greatest curse that's ever been inflicted on the human race, memory." -- Jed Leland (Joseph Cotten), "Citizen Kane" (1941)
Nearly every scene in "The Phantom," the Season 5 finale of "Mad Men," conjures a ghost from the show's past. "Mad Men," like many great series from "Hill Street Blues" to "SCTV" to "The Sopranos," has always been exceptionally good at this (see "The Long Walk"), setting images, gestures and emotions reverberating off one another across episodes and seasons. The series has a memory, and the curse of memory is a primary theme of "The Phantom," which is why the episode is composed as it is. As Nancy Sinatra sings in that final song:
You only live twice, or so it seems, One life for yourself and one for your dreams.
(Spoilers from here on out.)
That's a James Bond theme song, from "You Only Live Twice" (1967) -- and it's the second Bond theme we hear in the episode, after Herb Alpert & the Tijuana Brass bite into Burt Bacharach's theme from the James Bond parody "Casino Royale" (1967) at the weekday matinée where Don (the suave, masculine Bond of New York advertising) runs into Peggy. (The Beatles, who have figured prominently in Seasons 4 and 5, released "Help!" in 1965 and it was in part a 007 parody, too -- especially the John Barry-like orchestral music written by George Martin.) Echoes and repetitions are everywhere.
