Lust, Caution
Wang took a break in working on his music to film "Lust, Caution" (2007), an espionage thriller film directed by Ang Lee. He released a promotional single "Falling Leaves Return to Roots" on June 20, 2007 through Hito Radio, a month before the release of his twelfth studio album, "Change Me". "Falling Leaves Return to Roots" incorporated Broadway-influenced musical elements, with classical instrumental accompaniments, such as the violin and piano. When asked about the sudden change of music style, Wang explained that the inspiration behind the song was due to the influence of his portrayal of Kuang Yumin in "Lust, Caution". "In the past, I have only been releasing mainstream pop and chinked-out related hip hop. "Lust, Caution" made me return to 1930's Shanghai, re-living the moment."
