Cantonese feature films (also called "Cantonese clips") are different from Hong Kong films and Hong Kong dramas. Cantonese feature films refer to Cantonese feature films produced in the 1940s and 1970s. Most of them are mainly in black and white, with slow pace, mainly in folklore and street life. They prevailed in the 1950s and 1960s, and now only TVB Emerald Channel in Hong Kong will replay them at midnight. For the elderly who speak Cantonese, Cantonese feature films are as important and influential as three meals a day. Some Hong Kong films (such as New He is My Brother) and Hong Kong dramas (such as He is My Brother and Detective Li Qi) often draw lessons from the classic elements of Cantonese long dramas.

Cantonese feature films originated in the era when there were audio films in Guangdong. They began to be produced in the 1920s and 1930s, developed in the 40s, peaked in the 1950s and 1960s, and then declined sharply in the 1970s, eventually losing to Mandarin films and European and American films.

Due to political and historical reasons, Cantonese feature films only prevailed in Hong Kong and Macao, and Cantonese feature films became Hong Kong-made films at that time.

Limited by the technology and cost at that time, Cantonese feature films are mostly black and white, and some of them are colored, all of which are labeled with the word "color", such as colored Hu Bugui and colored Buddha.

Cantonese feature films are mostly about life, street life and so on. It can reflect the living conditions of the lower classes at that time, so it is very popular among the people. Because these films can evoke fond memories of the older generation, there are still people who are obsessed with Cantonese feature films.

Because of Cantonese feature films, a batch of Hong Kong film superstars have been created, some of which are still active on the screen, such as Suet Nei, Ceng Jiang, Chung Chow and Li Xiangqin.
