Rigor Mortis is a 2013 Hong Kong horror film directed by Juno Mak and produced by Takashi Shimizu.

Many of the former cast are featured in this film: Chin Siu-ho, Anthony Chan, Billy Lau and Richard Ng.

After Yau refuses to help, Chin returns to his room, and is ambushed by Gau, who performs a ritual on him that summons the twins.

Uncle Yin, investigating Tung's absence, interrupts their discussion as he is suspicious of Gau's knowledge of black magic.

Gau explains that he is terminally ill, and he had planned to bind the twin ghosts' souls in Tung's soulless body to gain power and extend his own life.

Enraged, she tracks down the jiangshi and attempts to destroy it using an improvised mace, but she is severely outmatched and it ultimately kills her.

Revived, the powerful ghost-infused jiangshi easily impales Chin through the stomach with a pole and leaves him for dead.

Using vampire hunting tools, Yau sets a trap that temporarily binds Tung to that location, allowing Chin to fight him.

Yau uses his tools to weaken Tung, but Chin is unable to gain the upper hand before the trap expires.

In reality, the film's characters are people Chin passed on the way to his apartment: Yang and Pak are friendly neighbors, Meiyi is a widow admiring a picture of a late Tung, and Yau is a neighbor who rushes in too late to save the hanged Chin.

[7] Clarence Tsui of The Hollywood Reporter called it "a lavish, heavy-handed retreading and reinvention of Hong Kong and Japanese horror-film tropes, saved from clinical inhumanity by its veteran cast.

"[3] Justin Chang of Variety described it as a "flashy, incoherent and virtually scare-free Hong Kong horror exercise".

[9] Martin Tsai of the Los Angeles Times wrote, "The film supplies a succession of hyper-stylized and potent set pieces without ever establishing any sort of internal logic.
