“Cloud Atlas” is a film spanning six separate eras, from imperialism in the South Pacific all the way to a post-apocalyptic future. There's a lot of Tom Hanks in this. Different Hankses from different eras (alterna-Hanks, if you will). Pay attention to Tom Hanks's hair.
Apparently, Apple is set to release an HD version of the trailer later today, but this will have to do for now.
