Marry My Dead Body (Chinese: 關於我和鬼變成家人的那件事) is a 2022 Taiwanese supernatural comedy mystery film directed by Cheng Wei-hao and starring Greg Hsu, Austin Lin, and Gingle Wang.

Scripted by Sharon Wu and Cheng Wei-Hao, the film is adapted from the original story outline by Lai Zhi-liang.

While collecting evidence from a car crash resulting from his current case, he mistakenly picks up a red envelope, a traditional method of entrapping someone into a ghost marriage.

With his ghostly partner in tow, he works with his fellow policewoman Lin Tzu-ching (Gingle Wang) to investigate a major case in their department.

[6][7] Cheng also cooperated with Sharon Wu, who wrote the television series In a Good Way (2013), to develop the initial script of Marry My Dead Body.

In November 2021, Cheng attended the Golden Horse Awards Nominee Party for The Soul, and revealed that he had started to prepare to shoot his next film.

[13] Greg Hsu, who was nominated for a Golden Bell Award for Best Leading Actor in a Television Series for Someday or One Day (2019), plays Wu Ming-han, a straight policeman who is passionate and impulsive in handling cases.

He said that Wu Ming-han was a challenging role for him, as there were several scenes where he felt embarrassed, including being naked on a flying wire, which made him feel like he had "fallen into the director's trap", but also an opportunity to push himself.

Austin stated he found it challenging to perform comedy well, and that Mao was the largest but the loneliest role he had ever played.

[6][13] Gingle Wang, who won a Taipei Film Award for Best Actress for Detention (2019), plays police officer Lin Tzu-ching.

In her role of a policewoman working among men, she stated that she wished to express how women are vulnerable to discrimination in current society.

[14][13] The film's theme song "Untitled" is performed by the Golden Melody Award-winner Jolin Tsai, who also participated in the songwriting and production.

Cheng said that Tsai is representative of Taiwan's LGBT culture and believes that her songs are suitable for the theme conveyed by the film.

Cheng Wei-hao, Veronica Jin, Dennis Wu, Greg Hsu, Austin Lin, and Gingle Wang all attended the premiere event.

[23][24] The film was adapted into a Thai film by GDH 559, titled "The Red Envelope" (Thai: ซองแดงแต่งผี Marry Ghost with The Red Envelope), starring Putthipong Assaratanakul as Wu and Krit Amnuaydechkorn as Mao, directed by Chayanop Boonprakob, scheduled for release on February 13, 2025.

[25] Cheng Wei-hao and Yin Chen-hao co-direct and co-wrote the series, with Greg Hsu, Gingle Wang, Ma Nien-hsien, and Chen Yen-tso reprising their roles.
