Crime Land

Pom Pom (神勇雙響炮; lit. "Supernaturally brave artillery") is a 1984 Hong Kong action comedy film directed by Joe Cheung. It is the first in a series of four Pom Pom films starring Richard Ng and John Shum.

The title of the film is the onomatopoeic representation of a gunshot sound. The title is sometimes suffixed with an exclamation mark as Pom Pom! and the alternate Hong Kong English title for the film is Boom Boom![1]

The film is something of a spinoff of Sammo Hung's Lucky Stars films, and Hung produced Pom Pom and released the film through his Bo Ho Films production company. Ng and Shum had been two of the original quintet of Lucky Stars in the film Winners and Sinners and their co-stars in that film, Hung, Charlie Chin and Stanley Fung make cameo appearances in Pom Pom as their characters from My Lucky Stars, released in the following year.

Jackie Chan and Yuen Biao, who had appeared in the original Lucky Stars trilogy also made cameo appearances as a motorcycle cop and truck driver respectively. The film also features appearances from several of their Hong Kong action film contemporaries, including Deanie Yip, Lam Ching Ying, Philip Chan, Dick Wei and Wu Ma.
