Jianyu Jianghu is a classic example of cross-cultural cooperation. Mandarin, Cantonese, Japanese, and English are all used in the workplace. Director of photography Horace Wong, martial arts choreographer Stephen Tung, and most of the key production staff are from Hong Kong. And the film itself is an even bigger production than Su's 2005 horror film Silk.
《劍雨江湖》是典型的亞洲跨文化合作，工作現場國語、廣東話、日語、英語混合使用，攝影師黃永恒、武術指導董瑋，以及其他基本製作班底多為香港人，這是蘇照彬繼 2005 年的驚悚片《詭絲》後另一部更大型製作。
