Shanghai is considered to be the birthplace of Chinese cinema. China's first short film, "The Difficult Couple" (1913), and the country's first fictional feature film, "An Orphan Rescues His Grandfather" (, 1923) were both produced in Shanghai. Shanghai's film industry grew during the early 1930s, generating stars such as Hu Die, Ruan Lingyu, Zhou Xuan, Jin Yan, and Zhao Dan. Another film star, Jiang Qing, went on to become Madame Mao Zedong. The exile of Shanghainese filmmakers and actors as a result of the Second Sino-Japanese War and the Communist revolution contributed enormously to the development of the Hong Kong film industry. The movie "In the Mood for Love" directed by Wong Kar-wai, a Shanghai native, depicts a slice of the displaced Shanghainese community in Hong Kong and the nostalgia for that era, featuring 1940s music by Zhou Xuan.
