All Men Are Brothers () is a 2011 Chinese television series adapted from the 14th-century classical novel Water Margin by Shi Nai'an, one of the Four Great Classical Novels of Chinese literature. The series is directed by Kuk Kwok-leung and features cast members from mainland China, Taiwan, and Hong Kong. The series was first broadcast on 8TV in March 2011 in Malaysia.
The music for the series was composed by Zhou Zhiyong ().
The Hong Kong release features a different opening and ending theme song from the original version. Both are sung in Cantonese.
Wu Ziniu was initially directing the series, but had switched to work on Great Porcelain Merchant as the shooting of All Men Are Brothers was delayed. He was replaced by Hong Kong television series director Kuk Kwok-leung. Art director Zheng Xiaolong said that he felt that Wu would be more suitable as the director, but he also expressed confidence in Kuk.
There were rumours that Fan Bingbing would be portraying Pan Jinlian. However, during the opening ceremony, Fan's spokesperson denied those claims and accused the production team of using Fan's name as a means of advertising the series. She added that Fan will only participate in projects her own company is involved in. Zheng Shuang, who played Hu Sanniang in The Water Margin (1997), also expressed interest in taking on the (more challenging) role of Pan Jinlian. However, Gan Tingting was eventually cast as Pan Jinlian.
Photos of actor Wu Yue dressed in ancient Chinese armour and posing in various martial arts stances appeared on the internet around late 2009. There were rumours about the photos being a preview to Lin Chong's character design in the upcoming All Men Are Brothers. Wu's spokesperson claimed that Wu did not receive an official invitation from the production team of All Men Are Brothers to join the project, although he did interact with them. The photos are actually part of a wuxia-themed series of pictures used to promote the 2008 Summer Olympics.
There were rumours that Deng Chao, Nie Yuan, Tong Dawei and Huang Xiaoming are part of the cast. Huang, who was initially a popular choice for the role of Yan Qing, claimed that he did not receive any notice and is unable to join the project due to his schedule. Deng was considered by Wu Ziniu for playing Song Jiang. Nie was initially confirmed to portray Lin Chong, but an online poll found that Nie ranked behind another actor, Yu Bo (), in terms of popularity for playing Lin Chong, even though the poll was not a factor in determining which actor would be cast. Both Nie and Deng had expressed interest in taking on the role of Ximen Qing.
