Code 46 is a 2003 British film directed by Michael Winterbottom, with screenplay by Frank Cottrell Boyce. It was produced by BBC Films and Revolution Films. It is a disquieting science fiction love story with themes that explore the moral impacts of advances in biotechnology. The soundtrack was composed by David Holmes under the name "Free Association". The film was shot in Dubai, Shanghai, Kuala Lumpur, Rajasthan (picturised as Jebel Ali) and many interiors in London, both for logistic reasons and because the juxtaposition of elements of these cities offered a believable futuristic setting.

Michael and Jenna, having been a couple for three years, want to get married and start a family. These plans seem to be well on their way when Jenna announces that she's pregnant. But Michael is worried that his life and his youth will be over for good. At a wedding of a friend, he meets a free-spirited college co-ed, Kim, who opens his eyes and leads him on a dangerous path away from Jenna. Meanwhile, none of the relationships of the people surrounding Michael and Jenna are happy and stable. Michael's friend Izzy is unwilling to let go of his childhood sweetheart Arianna; Kenny is a handsome stud who fears commitment to his latest conquest Danielle; and Chris is a co-worker who is dominated by his neurotic and overbearing wife over raising their newborn son. Even Jenna's parents, Stephen and Anna, are experiencing problems in their long-suffering marriage.
