Starring Teresa Mo, Ronald Cheng, Wong You-nam, Jennifer Yu, Edan Lui, Yeung Wai Lun, Lau Kong, and Bonnie Wong, the film revolves around a group of apartment residents trying to dispose of a mysterious corpse that has appeared on their floor to prevent their homes from becoming stigmatized properties and losing value.

The screenplay began development in March 2019 and was greenlit in October 2021, with Ho Cheuk Tin joining the project that same year, marking his second feature film after The Sparring Partner (2022).

Ming returns to his mother-in-law Meghan's apartment 14A in high-end private estate Seaside Heights after work, where he lives with his wife Yana and brother-in-law Kingston.

Without thoroughly checking whether the man is dead, Ming suggests calling the police, but Meghan immediately rejects this option, fearing their apartment will become stigmatized property, significantly losing value and complicating their already debt-ridden lives.

He pursues the residents of the 14th floor, who are moving the corpse to the rooftop, using a suspended working platform to transport it out of the building on Sue's advice.

[10] Louisa So and Jan Lamb, who previously starred in Ho Cheuk Tin's The Sparring Partner (2022), provide voice-overs as the narrator and for the advertisement of Seaside Heights respectively.

[13][14] Chin then began searching for suitable directors and was advised by filmmaker Philip Yung and actor Yeung Wai Lun to consider Ho Cheuk Tin, who had worked with them on the then-unreleased The Sparring Partner (2022).

[15] Ho accepted the invitation in 2021, despite The Sparring Partner being a dark thriller that contrasts with the comedic tone of Over My Dead Body, marking his second feature film.

[8] Approximately two-thirds of the film was shot in a studio,[27] while most of the location shooting took place in Tai Wai, Sha Tin District.

[4] Director Ho Cheuk Tin chose to set the film in Tai Wai, as it is a new town and logical to have a new housing estate as the setting, with the town only bisected by the canals of Shing Mun River instead of being situated near the sea, which serves as a sarcastic irony to the name of the housing estate, "Seaside Heights", featured in the film.

[28] The film's theme song "Salted Fish Game" was composed by Tsui Chin Hung, with lyrics by Wyman Wong and performed by Jer Lau.

[29] Director Ho Cheuk Tin deemed Lau's role, which was a cameo appearance in the film, too minor, so he also invited him to perform the theme song.

[40] Edmund Lee of South China Morning Post gave Over My Dead Body 3.5/5 stars, praising director Ho Cheuk Tin's raw talent and confidence in crafting a conceptually adventurous and aesthetically considered comedy-drama out of an unlikely but clever premise revolving around a political pun and the absurdities of Hong Kong's inflated property market.

[5] Jonathan Hung, in his review for am730, praised the film as a hilarious yet poignant black comedy that showcases the young director's bold and insightful approach to tackling the absurdities of Hong Kong society, with Hung noting the standout performances, particularly from actors Jiro Lee and Kenneth Cheung in minor roles, as well as the exceptionally written script and applaudable humour.

[6] Kwok Ching-yin of Esquire focused on the auteur approach of the filmmaker, noting the similarity between this film and Ho Cheuk Tin's previous entry The Sparring Partner in their exploration of generational and political conflict in Hong Kong through metaphors, introspection scenes, and word puns, but whereas The Sparring Partner had a tragic ending, Over My Dead Body offered a more optimistic resolution where the generations reconciled.
