Directors create new road map to 'Cloud Atlas' for film adaptation NEW YORK - As they swept through airports while making their ambitious, risky new movie, "Cloud Atlas," directors Andy and Lana Wachowski got used to answering a surprisingly tough question from customs officials. "They'd say, 'What's your movie about?'" said Andy. It's about the sum of human experience. They always look up and go, 'Oh, really...' "Our target audience is customs officials," whispered Lana. PHOTOS: Scenes from 'Cloud Atlas' Actually, their target audience is grown-ups. The Wachowski siblings made "Cloud Atlas" together with German director Tom Tykwer. If filmmaking were an Olympic sport, the trio would score maximum difficulty points for even attempting the project - their script, adapted from British author David Mitchell's bestselling, puzzle-like 2004 novel, vaults through six interwoven story lines spanning some 500 years and several genres, from a 19th century sea yarn to a 20th century thriller to a post-apocalyptic romance. "Hangover 2" it is not. The movie's sprawling narrative and independently financed $102-million budget required its three filmmakers to embark on a rocky, six-year search for financing and ultimately shoot on two sets at the same time, one helmed by the Wachowskis, the other by Tykwer.

All three share an earnestness and a sibling-like tendency to finish one another's sentences - even Tykwer, who was 34 when he met the Wachowskis. Lana, 47, has been on her own personal journey - she is transgender and until 2002 was called Larry. Bubbly and stylish, with fuchsia dreadlocks, black boots and a soft, breathy voice, she seems to be the spiritual leader of the group; Lana's younger brother, Andy, 44, is bald and barrel-chested and warier than his sister to talk but acerbically funny when he does; Tykwer, 47, is cerebral and handsome, with a heavy German accent. The threesome share similar origins stories. All started making short films as children - the Wachowskis, born in Chicago, found jobs in carpentry and comic books before they directed their first feature, "Bound," in 1996; Tykwer, born in Wuppertal, Germany, worked as a theater projectionist before his first feature, "Deadly Maria," came out in 1993. Friends since 1999, when Tykwer's defining crime thriller "Run Lola Run" opened in the U.S. within a few months of the Wachowskis' now iconic sci-fi action movie "The Matrix," the filmmakers had stayed in touch over the years, looking for a project to share. When Lana read "Cloud Atlas" in 2005, she saw in it the potential of deep-think, big-canvas films she and her brother had loved in their youth, like "2001: A Space Odyssey," and recommended the book to Andy and Tykwer. "There was a time when movies were funny and sad and dramatic and slapsticky and challenging and thought-provoking all at the same time," said Lana. That would be one movie. Now you break that all up into a comedy, a romance, a drama. With 'Cloud Atlas' we were thinking, 'It could be everything.' "We felt like, because it's so challenging it will need three directors," said Tykwer. It will help to have three minds! They put their minds together to tackle "Cloud Atlas'" complex structure, but it was Lana, inspired by a line in the book in which a character disdains "flashbacks and flashforwards and other tricksy gimmicks," who first came up with the solution. In the novel, the six interconnected stories unfold chronologically, until the middle of the book, where the sequence reverses. The unusual architecture of the story is part of the pleasure of reading "Cloud Atlas," but it's also what made the book seem unfilmable - who would want to watch characters for 20 minutes who then disappear for two hours? Instead, Lana proposed to her co-writers a structure in which all of the stories unravel concurrently and wrote the first 10 minutes of the film this way to persuade them. To help clarify the book's underlying metaphysical themes, the directors came up with another "tricksy gimmick" - having their actors, who include Tom Hanks, Halle Berry, Hugh Grant and Korean star Doona Bae, each play multiple roles. Sometimes they portray different races and genders. "We wanted this feeling that we'd get the dissolution of borders and boundaries," Lana said. The whole system of understanding what the other is - man, woman, white, black, Western, Asian - there are all these barriers to understanding the human-ness that's underneath these distinctions. The filmmakers were able to attract name actors such as Hanks and Berry because the stars would get to play multiple intriguing roles. Financiers were a tougher sell. "People were blown away by the concept and blown away by the cast, but they wouldn't give us any money," Andy said.
