Early in the film Raiders of the Lost Ark, we watch a path appear on a map to represent the movement of characters across the earth.
This scene reminded me of the animation at the beginning of Casablanca, which accompanies the voice-over description of motion of refugees:
And so a tortuous, round-about refugee trail sprang up. Paris to Marseilles, across the Mediterranean to Oran [in Algeria], then by train or auto or foot across the rim of Africa to Casablanca in French Morocco. Here the fortunate ones through money or influence or luck might obtain exit visas and scurry to Lisbon, and from Lisbon to the New World. But the others wait in Casablanca, and wait...and wait...and wait.
This strikes me as a film cliche, similar to the turning-pages-of-the-calendar device to express the passage of time.
But the truth is, I cannot think of any other movie that uses this path-on-the-map device. Is it simply a visual reference to Casablanca, or a bona fide cliche? Where did the path-on-the-map device first appear?
