Born in Denmark, filmmaker Christian E. Christiansen began career by producing a series of short films in the early 2000s. In 2005, he went on to produce the feature-length comedy "Nynne," and the next year, he stepped into the director's chair for "Life Hits," a gritty coming of age drama about adolescent girls, which he also wrote. Following "Life Hits," Christiansen continued to write and direct, helming the 2007 short "At Night." The film explored the bonds that develop between a group of young women stricken with cancer, and it earned Christiansen an Oscar nomination for Best Short Film. Christiansen next decided to expand the short into the feature film "Crying For Love," which was released in 2008. The following year, the writer/director opted for lighter fare, making "Zoomers," a comedy that chronicled the friendship and adventures of two teen boys. Two years later, Christiansen made his first American film, the Hollywood thriller "The Roommate," which featured young stars Leighton Meester, Minka Kelly and Cam Gigandet. Despite receiving scathing reviews from critics, "The Roommate" became a modest box office success. Christiansen also released a suspense film in his native Denmark in 2011, "ID:A," which tracked the plight of a young woman reeling from amnesia.
