Warriors Two is a 1978 Hong Kong martial arts film written and directed by Sammo Hung, who also co-stars in the film. The film stars Bryan Leung, Casanova Wong and Fung Hak-on. Leung plays the character of the historical figure, Leung Jan (or Leung Tsan), a well-known early practitioner of the Wing Chun style of kung fu. Leung's association with Wing Chun can be considered as the equivalent of Wong Fei-hung's association with the Hung Gar style.
Along with The Prodigal Son, Warriors Two is considered one of the best martial arts film displaying the authentic version of the Wing Chun style. Despite the title, Warriors Two is not a sequel. Rather it refers to the two main warriors of the film, and the literal translation of the Hong Kong title is "Mr. Tsang and Cashier Hua".
