The Warlords (投名狀), previously known as The Blood Brothers, is a 2007 Chinese–Hong Kong epic historical action film directed and co-produced by Peter Chan, starring Jet Li, Andy Lau, Takeshi Kaneshiro and Xu Jinglei.

For the film, Li became the highest paid actor in a Chinese-language movie, previously holding the record for his part in Hero (2002).

He meets and befriends Zhao Erhu and Jiang Wuyang, the leaders of a bandit gang based in a nearby village, and joins them in raiding a rebel convoy for food supplies.

Since the villagers are poor and starving, Pang convinces them to form a militia and join imperial forces to suppress the rebellion.

With Pang as their leader, the three men swear a blood oath and pledge loyalty to each other as brothers on the pain of death.

As a result, the battle of Suzhou turns into a year-long siege in which the militia gradually runs out of food and supplies.

After the Battle of Nanjing which marks the end of the war, Pang is rewarded with the position of a viceroy by the imperial government.

Offscreen, it is mentioned that Jiang is eventually arrested, made the scapegoat for Pang's assassination, and executed by lingchi.

Director Peter Chan said it was influenced by Chang Cheh's 1973 film The Blood Brothers, which was based on a high-profile assassination of a local governor in 1870, but denied that it is a remake.

Wang claimed that in a short promotional video shown during a press conference held on 11 December 2006 in Beijing, the film company used ten pieces of his work with minor alterations.

[13] Perry Lam of Muse has also given the film a generally positive review, praising it for taking "a clear-eyed but sympathetic look at its flawed heroes".
