As noted on the website movie-censorship, there is a longer edition of the film, with extra scenes filmed in Shanghai, specially edited for release in China. Scenes were originally to take place in Paris, but were moved to secure support of Chinese financiers. The worldwide version of the film featured too few scenes in Shanghai for them, despite that fact that test screenings with American audiences showed them to upset the film's pacing. The scenes are mainly exposition about how Gordon-Levitt's character took a downward spiral. Said one of the two people involved with the film., "But the Chinese didn't care about pacing, and they wanted the [China-set] scenes in, so we said OK."
