Cloud Atlas is a 2012 science fiction film written and directed by the Wachowski Sisters and Tom Tykwer. Adapted from the 2004 novel of the same name by David Mitchell, the film has multiple plots occurring during six different eras in time; Mitchell described it as "a sort of pointillist mosaic." The film's synopsis describes it as "an exploration of how the actions of individual lives impact one another in the past, present and future, as one soul is shaped from a killer into a hero, and an act of kindness ripples across centuries to inspire a revolution." Tom Hanks, Halle Berry, and Jim Broadbent star as part of an ensemble cast.
The film was produced by Grant Hill and Stefan Arndt, in addition to the Wachowskis and Tykwer. During its four years of development, the project met with some difficulties in securing financial support. However, the film was eventually produced with a US$128.5 million net budget provided by independent sources, making it one of the most expensive independent films ever produced. Production for Cloud Atlas began in September 2011 at Babelsberg Studio in Potsdam-Babelsberg, Germany.
