I Actually Stayed Up Very Late This Morning To Rewatch Temple Of Doom.

Specifically for a Metropolis analysis. 

I'd forgotten how deep the influences run. The mine where the children are mining the Sankara Stones is blatantly Mother Mary's catacombs Temple.

In Metropolis Rotwang claims to have lost his hand creating Machine Man. Something illustrated by him wearing a black glove over the supposedly lost hand. An early attempt at special effects. To convey his madness he does this weird, almost, mime where he draws attention to the gloved hand, paralysed as a claw.

When Indiana Jones is forced to drink the blood potion, turning him into a Thugee automaton he does the same weird claw mime.

Metropolis is a tale of two cities. However those two cities can really be divided into for modules; the catacombs, the worker's dormatories, the machine module and the Surface city.

Obviously Metropolis is a vertical city. A metaphor for a class-divided hierarchical society. Rather than a egalitarian, Communist, society. So when the workers travel between the dormitory and machine modules and they march along these underground tunnels then climb into electric elevator cars.

This is a vertical version of the newly invented underground railways, subways.

When I write about the London Underground I have to explain it using the internationally recognised term; "Metro."

The reason why that's the internationally recognised term is because the first line of the London Underground built was The Metropolitan Line (electrified in 1905). Paris was so inspired they decided to build their own and many others followed. However the expansion of the London Underground meant the term fell out of use in the city which invented it.
