The Diary of a Big Man

The story unfolds primarily in Hong Kong, the bustling urban center where Chow maintains his double life. The film also travels to Paris and the United States, which serve as romantic backdrops for his two wives' separate lives. These contrasting locations highlight the farcical nature of his schemes, juxtaposing local Hong Kong chaos with Western romance.

The film explores several interconnected themes: bigamy and deceit, where elaborate lies gradually destroy trust; identity and masks, as characters adopt false personas to hide the truth; female solidarity, as the two wives unite against their shared deception; and comic chaos, using farce and misdirection to drive the comedy. The central message warns how deceit ultimately corrodes personal relationships despite outward confidence.

Chow Ting-fat is the charismatic bigamist at the center, juggling two wives through elaborate schedules and lies. His two wives are Joey, a boutique owner, and Sally, an air-hostess. Chi Hung is Chow's loyal but overwhelmed best friend and accomplice, while Ka Lai is Chi Hung's suspicious girlfriend. Inspector Cheng is the police officer who investigates Chow's deception, adding tension to the comedic chaos.

The movie is set in the late 1980s, reflecting the era of its 1988 release. The contemporary Hong Kong setting features neon-drenched urban landscapes and modern city life, placing the story in a cosmopolitan Asian metropolis at a time when the territory was experiencing significant economic and cultural growth.

The theme of bigamy and deceit examines how Chow's attempt to maintain two marriages through elaborate schedules and lies eventually unravels. The humor emerges from increasingly improbable schemes that collapse under scrutiny. Rather than celebrating the deception, the film shows how lying damages trust and disrupts lives, even though Chow remains outwardly confident throughout.

When Joey and Sally discover Chow's deception, they transform from rivals into allies. Initially unaware or skeptical, they ultimately confront Chow together, combining their strength and wit to exact revenge. This female solidarity demonstrates independence and agency, showing women can unite to reclaim power in chaotic situations created by male deceit.

This is a romantic comedy with farce elements, featuring misdirection, slapstick, and over-the-top set pieces in hotel rooms and public spaces. The tone is predominantly light and comedic, with fast pacing driven by constant near-discoveries and improvised lies. While the tension from risk of exposure is high, it resolves through comedy, keeping the emotional weight light despite the betrayal themes.

Chi Hung serves as Chow's best friend and loyal accomplice, orchestrating alibis and helping maintain the double life. However, he becomes overwhelmed by the deception and his own insecurities create additional tension. His subplot adds comedic vulnerability to the narrative, and his relationship with Ka Lai reflects the broader theme of infidelity's impact on those surrounding the central trio.

The identity and masks theme shows how Chow and Chi Hung adopt false identities to conceal the truth, turning social roles into movable disguises. The film stages a series of excuses, disguises, and mistaken assumptions that expose how fragile personal truth can be. This interplay between performance and reality questions whether relationships built on deception can ever be genuine.

Inspector Cheng is the police officer who becomes suspicious of Chow's entanglement with two wives. His investigations drive much of the plot's tension as he repeatedly collides with Chow's evasive tactics. His presence introduces an element of law and order that contrasts with the playful chaos of the romantic farce, adding a dimension of external threat to the comedic scenario.

Chow Ting-fat is a charismatic but scheming bigamist who dreams of wealth and multiple romances. He relies on intricate timetables and excuses to keep his two wives from discovering each other, though his plans constantly teeter on the brink of collapse. His charm masks recklessness, as he misreads loyalty and consequence, leading to both comic and painful consequences.

The film features fast pacing with a constant stream of near-discoveries, improvised lies, and chaotic set pieces that keep the plot moving briskly. The narrative uses classic farce structure with escalating absurdity, though the complexity remains moderate and accessible. The ending is bittersweet, blending sincere apology with ambiguous resolution, leaving room for both remorse and hope.
