It's an alternate-history anime featuring Dr. John Waston (yes, that one) working for the British government trying to find the lost notebook of Victor Frankenstein. In a world where reanimated corpses have become cheap labor.
Yup, a steampunk zombie movie from Japan. I loved it; it was gorgeous and ridiculous and utterly fascinating.
In no particular order there was:
John Waston, who has stolen and reanimated his friend's corpse.
M/Walsingham, the head of a British intelligence agency who blackmails John into working for him
Friday/Noble Savage-007, the aforementioned friend as a reanimated corpse; Watson has programed him to act as scribe
The Nautilus, in a moment of sheer WTF?!
An automaton that just wants a soul
A cameo by Thomas Edison
Babbage analytical engines directing corpse labor
Analytical engines running on punch cards with input/output by manual typewriter
Ulysses S Grant in Japan
Alexei Karamazov as Russian corpse-engineer who has stolen the Frankenstein notebook and run off to Afghanistan
Nikolai Krasotkin as a Russian agent sent to track down Alexei Karamazov
A battle at the Khyber Pass, as enacted by armies of reanimated corpses
Frederick Burnaby, who is assigned as Watson's handler/bodyguard
The British super-computer/analytical engine is named Charles Babbage
The American one, in San Francisco, is named Paul Bunyan
Frankenstein's actual monster
Universal Horror's version of Frankenstein's monster
A Japanese military officer with truly outrageous eyebrows
A woman on top of a stagecoach, wielding a flamethrower
Zombie shinto monks as scribes for a Japanese corporation's analytical engine
Security hacking of reanimated corpses and with reanimated corpses
A villain who wants everyone in the world turned into a reanimated corpse, because that's the way to peace...uhm, no?
Corpse-bomb, because what's creepier than reanimated corpses? Reanimated corpses that explode!
A trip around the world from London, to Afghanistan, to Japan, to San Francisco, and then finally back to London (by submarine? from San Francisco?!)
Frankenstein's brain, in a jar!
It was like someone had put 19th century European literature and history in a blender, and then filtered it through Japanese anime.
I want more of it, possibly in crossover with Alan Moore's The League of Extraordinary Gentlemen, possibly just a 5000 word essay on how abundant corpse labor would have transformed Victorian culture, with special focus on the effects on the working class of being replaced by undead factory workers, on death and dying when bodies might be reanimated, and on the leisure class when half your servants are dead.
