The Swordsman (), also known as Swordsman, is a 1990 Hong Kong wuxia film loosely adapted from the novel The Smiling Proud Wanderer by Jin Yong. King Hu was credited as the director although he allegedly left the project midway, and the film was completed by a team led by producer Tsui Hark. It was followed by two sequels: Swordsman II (1992) and The East Is Red (1993).
The story is set in 16th-century China. Gu Jinfu, a eunuch from the Eastern Depot, is sent to retrieve the Sunflower Manual, a martial arts manual stolen from the imperial palace. They track down and attack the thief, Lin Zhennan. Around this time, Linghu Chong and Yue Lingshan, members of the Mount Hua Sect, save Lin Zhennan. Before succumbing to his wounds, Lin Zhennan tells them to inform his son, Lin Pingzhi, where he had hidden the manual.
On their way to rendezvous with their Mount Hua Sect fellows, Linghu Chong and Yue Lingshan chance upon Liu Zhengfeng and Qu Yang, who are retiring from the jianghu. Just then, Zuo Lengshan of the Eastern Depot shows up with his men and tries to arrest Liu Zhengfeng and Qu Yang. Linghu Chong and the others manage to escape, but Liu Zhengfeng and Qu Yang are seriously wounded in the process. Before committing suicide, the duo perform "Xiaoao Jianghu", a musical piece they composed together, and pass their instruments and the score to Linghu Chong.
Linghu Chong encounters the reclusive swordsman Feng Qingyang and learns the skill "Nine Swords of Dugu" from him. He also finds out that his gentlemanly master, Yue Buqun, is actually a power-hungry hypocrite. In the meantime, Gu Jinfu's henchman, Ouyang Quan, impersonates the dead Lin Pingzhi and infiltrates the Mount Hua Sect. He tricks Linghu Chong into revealing the whereabouts of the Sunflower Manual and then poisons him. Linghu Chong is saved by Ren Yingying and Lan Fenghuang of the Sun Moon Holy Cult. They combine forces to defeat and kill Zuo Lengshan and his men.
Around the same time, Yue Buqun, Ouyang Quan, Gu Jinfu and the others have arrived at the location where the Sunflower Manual is hidden and are fighting over the manual. Linghu Chong shows up, kills Gu Jinfu, exposes Yue Buqun's treachery and defeats him. He decides to spend the rest of his life roaming the jianghu with his friends.
The theme song, "A Sound of Laughter in the Vast Sea" (), was composed by James Wong, who also wrote its lyrics, and performed in Cantonese by Samuel Hui and also in Mandarin by Lo Ta-Yu, James Wong and Tsui Hark.
The film grossed HK$16,052,552 at the Hong Kong box office.
