Been thinking about Cloud Atlas a lot since yesterday - it's one of those films. One of the things I've been going through in my mind is the physical (sort of) connections between each story rather than the thematic. Here's what I've got, have I missed anything? (I'm sure I have)
1800s Adam Ewing's journal turns up as a book 1930's Robert Frobisher is reading, with a quick shot of the 'lost' half propping up a table leg which I thought was a really nice touch.
Frobisher's composition, the Cloud Atlas Sextet is mentioned in the Sixsmith letters that Luisa Rey is reading in the 1970s and she later buys a copy (from Ben Whishaw playing a record store cashier). Of course the older Sixsmith also features in the Luisa Rey storyline.
Timothy Cavendish in 2012 is seen reading a manuscript written by Luisa Rey's young friend Javier called the Luisa Rey Adventures (or something like that).
Cavendish's novel about his escape from the old people's home gets made into a film which is what Sonmi 451 is watching in the futuristic Korea and Sonmi's revolutionary speeches become the basis for a doctrine by which the tribes of 'The Big Island" after "The Fall" live by.
