The film stars Ajith Kumar, Arjun Sarja, Trisha Krishnan, Regina Cassandra, Arav and Ramya Subramanian.

[6] Arjun, originally from Chennai, works for a US-based firm initially in Tbilisi, Georgia, where Kayal was born and brought up.

Rakshith instructs Arjun to retrieve a hefty sum of money from his bank account and leaves him at the mercy of his henchmen.

Arjun saves the injured sheriff and takes his car, and then leaves to confront Jabbar and his friends who then reveal that Rakshith is housed in a dilapidated factory with his gang where he is disposing off evidence.

While Arjun escapes with few injuries, Deepika falls into an acid vat, burning half of her face off, screaming in the process.

However, Arjun overpowers him and hangs him by the crusher, demanding Kayal's whereabouts in exchange to sparing Rakshith's life and not tell the police anything about it.

With no available leads on Kayal's whereabouts, Arjun desperately calls out for her around the factory premises and wearily collapses; he then notices two dogs digging through the ground and it reveals a trapdoor to an underground bunker.

Later, when the police arrive at the scene, a psychiatrist reveals to Arjun that both Rakshith and Deepika were psychopaths in his asylum and had escaped custody, killed Deepika's parents for abandoning her at the asylum and established a crime syndicate where they abducted wealthy couples, separating them and killing the husbands and performing plastic surgery on the wives to be sold to the Russians and they had been doing this for over 10 years.

[13] However, the following January, Vignesh was dropped from the project, reportedly because Ajith was not impressed with the script after the director had developed it during the pre-production for six months.

In February 2023, it was reported that Magizh had flown to London, where Ajith was at the time, and narrated a script which impressed the actor.

[19] During the promotions of the film, Magizh stated that Ajith suggested using the core idea of the source material, making Vidaamuyarchi his first directorial based on another person's story.

[22] In mid-February 2023, Nirav Shah was announced as the cinematographer, in his first film with Magizh and fifth with Ajith after Billa (2007), Nerkonda Paarvai (2019), Valimai (2022) and Thunivu (2023).

[24] Anirudh Ravichander would score the music, in his first film with the director, whilst Magizh's norm editor N. B. Srikanth was retained.

[17][25] In addition to his usual salt-and-pepper look, Ajith would sport a full-black hairstyle for his character in flashback portions, with certain scenes shot after his weight loss regime due to his involvement in the 24H Series.

[26][27] Sanjay Dutt was initially reported to play the main antagonist in his second Tamil film after Leo (2023).

[29][33] Tamannaah Bhatia was initially reported to play the female lead; however, Trisha, who would pair opposite Ajith for the fifth time following Ji (2005), Kireedam (2007), Mankatha and Yennai Arindhaal (2015), was instead announced.

[38] In July 2024, Azerbaijini media reported that several local actors were a part of the film including Vidadi Hasanov and Javanshir Hadiyev.

[8] In August 2024, the production house announced the involvement of actors Nikhil Nair, Ganesh Saravanan and Dasarathi in prominent roles.

[41] Initially, filming was intended to begin in the first week of September 2023 but was delayed due to Ajith's commitments to his world tour.

[55] Production was expected to resume in the last week of May,[55] but was delayed as Ajith had started filming for Adhik Ravichandran's Good Bad Ugly (2025) in Hyderabad.

[83][84] Ankit Oljha of The National News gave 4/5 stars and wrote that the "overall winner" was the director, "who helms a glossy big-budget thrill-a-minute joyride, and gives everything a chance to shine, from its lead star's screen presence and the gritty action sequences to the excellent character work and focused storytelling.

"[85] Goutham S of Pinkvilla gave 3.5/5 stars and wrote "If you're looking to enjoy an action flick driven by Ajith's presence, Vidaamuyarchi is worth watching, offering an engaging experience for both fans and general audiences alike.

"[64] Sudhir Srinivasan of Cinema Express gave 3.5/5 stars and wrote "Vidaamuyarchi is not a film about a hero who smashes his enemies into dust.

"[87] Janani K of India Today gave 3/5 stars and wrote "Vidaamuyarchi lacked an emotional arc and some solid twists and turns.

"[88] Kirubhakar Purushothaman of News18 gave 3/5 stars and wrote "Vidaamuyarchi is largely engaging throughout despite the predictability, and the credit goes to Magizh Thirumeni, who is exceptional in his smooth expositions.

"[89] Anusha Sundar of OTTPlay gave 3/5 stars and wrote "With gripping action sequences, a well-structured screenplay, and an understanding of story sense, Vidaamuyarchi is not your typical star-driven film.

"[90] Sridevi S of The Times of India gave 2.5/5 stars and wrote "Vidaamuyarchi might find its space with some niche audience, but a racy screenplay, especially considering the genre, could have made the movie dearer to all.

The basic plot is painfully simple and predictable, and the makers' attempts to add tension fall flat as we see a fair share of twists coming a mile away.

"[92] Latha Srinivasan of Hindustan Times appreciated the cinematography but criticised the music, action sequences and felt the editing could have been "tighter".

[97][98] However, Chitra Lakshmanan, who was in contact with the makers, claimed they had brought the remake rights three months prior upon noticing the similarities between both films.
