Cloud Atlas is a 2012 epic science fiction film written and directed by the Wachowskis and Tom Tykwer. Based on the 2004 novel by David Mitchell, it has multiple plots occurring during six eras and features an ensemble cast who perform multiple roles across these time periods.

The film was produced by Grant Hill and Stefan Arndt, in addition to the Wachowskis and Tykwer. During its four years of development, the producers had difficulties securing financial support. It was eventually produced with a budget between US$100 million and US$146.7 million provided by independent sources, making it one of the most expensive independent films ever produced. Filming for Cloud Atlas began in September 2011 at Babelsberg Studio in Potsdam-Babelsberg, Germany.

It premiered on 8 September 2012 at the 37th Toronto International Film Festival, and was publicly released on 26 October 2012 in conventional and IMAX cinemas. Critics were polarized, causing it to be included on various "Best Film" and "Worst Film" lists. It was nominated for a Golden Globe Award for Best Original Score for Tykwer (who co-scored the film), Johnny Klimek, and Reinhold Heil. It received several nominations at the Saturn Awards, including Best Science Fiction Film, and won for Best Editing and Best Make-up.
