Seven Swords is a 2005 wuxia film produced and directed by Tsui Hark, starring Donnie Yen, Leon Lai, Charlie Yeung, Sun Honglei, Lu Yi and Kim So-yeon. An international co-production between Hong Kong, China, South Korea and the Netherlands, the story is loosely adapted from Liang Yusheng's novel Qijian Xia Tianshan and is completely unrelated to the novel except for some characters' names. Seven Swords was used as the opening film to the 2005 Venice Film Festival and as a homage to Akira Kurosawa's 1954 film Seven Samurai.
