In April 2009, it was announced that Spring Fever was to be shown in competition at the 2009 Cannes Film Festival. Little else was known about the film at the time, except that Lou was in the process of editing the film in Paris. Like Summer Palace, Spring Fever was to be screened without government approval.
By the time of the film's premiere at the Cannes Festival on May 13, 2009, it was known that Lou had circumvented the five-year ban imposed upon him after Summer Palace by having Spring Fever registered as a Hong Kong/French co-production, and by secretly filming in Nanjing.
China, 2007. Spring. As Nature gradually awakens and an intoxicating spring breeze full of life blows, as they drive together to the coast, love and sexual passion grow in the hearts of Jiang Cheng, his friend Luo Haitao and Xiaoxue, a beautiful young woman. All three fall prey to an exhilarating sickness of the senses, a dangerous malady that misleads the heart… A beautiful erotic "menage à trois".
An early review by industry watcher Variety, following Spring Fever's premiere in the 2009 Cannes Film Festival, was critical with the film's "overlong" running-length of 116 minutes, and its overly "Euro tastes (and Western sensibilities)," especially when compared with Lou's breakout film of Suzhou River.
The film won the award for Best Screenplay at the 2009 Cannes Film Festival.
