The Debt Collector cast is led by Nadech Kugimiya as Num, Daou Pittaya Saechua as Po and Chaiwat Thongsaeng as Kong. Nuanprang Trichit plays crime matriarch Madam Pin, while Netflix also credits Johnathan Holman, Ploypaphas Fonkaewsiwaporn, Kunkanit Khumkrong, Nuttanan Kunnawatt, Paphon Jirahitapat and Piyaphong Vongkamlao in supporting roles.
Netflix’s Thai action thriller The Debt Collector works because its actors treat the story as more than a revenge movie. The film has brutal confrontations and long fight sequences, but its central conflict is built around guilt, family loyalty, exploitation and the possibility of redemption. The performers therefore have to make the emotional consequences feel as important as the physical danger.
Nadech Kugimiya carries the story as Num, a former underground debt collector who leaves prison with a terminal diagnosis and a desire to stop the system he once helped enforce. Daou Pittaya Saechua plays Po, the volatile heir to that violent system, while Chaiwat Thongsaeng appears as Kong, a police officer investigating crimes connected to illegal lending. Their characters approach the same criminal world from very different positions.
This guide focuses on the actors, characters and performances. For the full plot, verdict and ending, read our The Debt Collector Netflix review and ending explained.

Netflix’s public cast list confirms the supporting performers, but not every supporting character name has been published in dependable English-language credits. This article therefore avoids assigning unverified roles.
Nadech Kugimiya as Num
Nadech Kugimiya plays Num, the former debt collector at the centre of the movie. Num once used intimidation and violence for a criminal lending operation. A long prison sentence and a terminal illness leave him with limited time, but neither experience erases the harm he caused. His decision to return to the underworld is driven by a need to protect vulnerable borrowers and confront the people who continue exploiting them.
The role is a sharp change from the polished romantic image many viewers associate with Nadech. Netflix described the part as one of the biggest transformations of his career. The actor appears with scars, tattoos, weathered skin and an exhausted physical presence that makes Num look like a man who has already survived more than he expected to.
Nadech’s performance is deliberately restrained. Num does not explain every feeling in dialogue. His guilt appears through pauses, posture and the way he reacts when innocent people are threatened. That quiet approach helps the character avoid becoming a conventional invincible action hero. Num is dangerous, but he is also sick, frightened and aware that a final act of violence cannot completely repay the moral debt of his past.
Viewers may recognise Nadech from the Death Whisperer horror films, The Crown Princess, Doctor Detective and several major Thai romantic dramas. The Debt Collector is his Netflix movie debut and gives international audiences a very different introduction to his range.
Daou Pittaya Saechua as Po
Daou Pittaya Saechua plays Po, the son of a powerful loan shark. Po wants authority, recognition and control, but his ambition is not matched by emotional discipline. He treats fear as proof of strength and becomes more dangerous whenever his status is questioned.
Po is the natural opposite of Num. Num has seen where violence leads and wants to stop repeating his past. Po is still attracted to the power that violence appears to provide. Their conflict is therefore not only a battle between hero and villain. It is a collision between a man trying to leave a destructive system and a younger man determined to inherit it.
Daou is widely known as a singer and former member of the Thai boy group LAZ1, as well as for romantic dramas including Love in Translation and Century of Love. The Debt Collector gives him a darker screen persona. Netflix noted that Daou wanted viewers to believe the character strongly enough to dislike him, and the performance leans into Po’s insecurity rather than presenting him as a calm criminal mastermind.
That choice makes Po more unpredictable. He can shift from confidence to rage when events move outside his control. Daou’s younger, more expressive energy also creates an effective contrast with Nadech’s physical stillness and emotional restraint.
Chaiwat Thongsaeng as Kong
Chaiwat Thongsaeng plays Kong, a police officer dealing with crimes linked to loan sharks and illegal debt collection. Kong occupies a different place in the story because he represents formal law enforcement rather than either side of the criminal operation.
His presence expands the film beyond Num’s personal revenge mission. The violence around illegal lending is not shown as an isolated feud between two men. It is part of a larger network involving victims, collectors, criminal leaders and authorities trying to understand or contain the damage.
Chaiwat, sometimes credited as Tob Chaiwat Thongsaeng, has appeared in Thai films and television projects including Doctor Climax and The Iron Ladies. His grounded screen presence supports the procedural side of The Debt Collector and prevents the story from becoming entirely centred on Num and Po’s rivalry.
Nuanprang Trichit as Madam Pin
Nuanprang Trichit plays Madam Pin, the crime matriarch connected to Num’s former life and Po’s rise. She represents the established power behind the lending operation. While Po is impulsive and eager to prove himself, Madam Pin understands how fear, family loyalty and financial dependency can be used to maintain control.
The character also complicates the film’s family dynamics. Po’s behaviour does not develop in isolation. He is shaped by a criminal structure that treats cruelty as authority and inheritance as entitlement. Madam Pin’s relationship with Num carries the weight of his history, while her relationship with Po helps explain why he believes the organisation belongs to him.
Nuanprang is a veteran Thai performer with a career across television and historical drama. Her experience gives Madam Pin a composed authority that balances Daou’s more openly volatile performance.
The supporting cast of The Debt Collector
Netflix lists a wider ensemble around the four central characters. Public English-language credits do not yet attach reliable character names to every actor, but the supporting cast helps create the film’s world of borrowers, families, enforcers and people caught between criminal and legal systems.
Ploypaphas Fonkaewsiwaporn
Ploypaphas Fonkaewsiwaporn appears in a supporting role. Netflix viewers may recognise her from the Thai mystery series Don’t Come Home, while her other credits include Ta Khon: The Cursed Mask. Her presence connects The Debt Collector with the growing group of Thai performers reaching a wider international audience through Netflix releases.
Kunkanit Khumkrong
Kunkanit Khumkrong is part of the supporting ensemble and previously worked in Cracked, another project directed by Surapong Ploensang. That earlier collaboration is useful because The Debt Collector depends on performers who can move between quiet dramatic scenes and sudden violence without changing the grounded tone.
Johnathan Holman, Nuttanan Kunnawatt and Paphon Jirahitapat
Johnathan Holman, Nuttanan Kunnawatt and Paphon Jirahitapat are also included in Netflix’s official cast list. Their public character descriptions remain limited, so the safest approach is to identify them as confirmed supporting performers rather than guess their relationships to Num, Po or Kong.
Piyaphong Vongkamlao
Piyaphong Vongkamlao completes the principal supporting list published by Netflix. Like several ensemble members, his role contributes to the wider social environment around the lending operation rather than replacing the central focus on Num’s attempt at redemption.
Why the cast works so well together
The lead performances create a generational conflict
Nadech and Daou are effective together because they play men at opposite stages of the same cycle. Num has already lived through the consequences of serving violent power. Po is still seduced by the status it promises. The age and performance contrast makes their confrontation feel like a warning about what Po may become as much as a reckoning with what Num used to be.
The actors keep the action emotionally grounded
Director Surapong Ploensang designed the action to carry moral weight. The cast supports that aim by showing fear, exhaustion and consequence after the fights. Num is not refreshed after every confrontation, victims do not become background decoration and even powerful criminals react when control begins to collapse.
The ensemble makes the debt metaphor larger
Every major character carries a different form of debt. Num carries guilt. Po believes power is owed to him. Madam Pin protects an organisation built on financial dependency. Kong faces the limits of law enforcement when violence is embedded in a wider system. The cast gives each version of debt a distinct emotional shape.

Is this connected to the 2018 movie The Debt Collector?
No. Netflix’s 2026 Thai film is unrelated to the 2018 American action movie The Debt Collector starring Scott Adkins and Louis Mandylor. The two productions share an English title, but they have different characters, stories, countries of origin and creative teams. Searching by the Thai original title, Khon Dueat Thuang Khaen, can help distinguish the Netflix release.
Where can you watch The Debt Collector?

Final thoughts
The Debt Collector cast gives a familiar revenge framework more emotional weight than its premise initially suggests. Nadech Kugimiya anchors the movie with a controlled, physically transformed performance as Num. Daou Pittaya Saechua makes Po unstable and threatening without turning him into a one-note villain. Chaiwat Thongsaeng and Nuanprang Trichit broaden the conflict through law enforcement and family power, while the supporting ensemble makes the consequences feel social rather than purely personal.
The result is a cast-driven Thai action film in which every confrontation reflects a different kind of debt. Viewers may come for the fights, but the performances are what make Num’s final attempt to change meaningful.
