Cold-heart) is a 2014 Indian Tamil-language crime comedy film written and directed by Karthik Subbaraj and produced by S. Kathiresan.

The film stars Bobby Simha, Siddharth, Lakshmi Menon, Karunakaran, Guru Somasundaram and Aadukalam Naren.

[2] Gavemic U. Ary was the cinematographer, making his debut in Tamil cinema, and Vivek Harshan was the editor.

Short film director Karthik Subramani participates in a talent show in order to make his first feature and reaches the semifinal round.

Karthik decides to document the life of "Assault" Sethu, a gangster based in Madurai, and make a screenplay out of it.

Karthik travels to Madurai and enlists the help of a college friend Oorani to conduct surveillance on Sethu and his men.

They eventually arouse the suspicion of Sethu's right-hand man Rasu, who puts underling Sounder to watch them.

Realising that a serious gangster film featuring Sethu would not succeed, Karthik had surreptitiously changed the story into a comedy.

Sethu and Karthik eventually meet by accident, as the latter is en route to deliver recordings of the former's boastful confessions to the police.

[7] Karthik Subbaraj confirmed the same shortly thereafter, noting that although the script was complete, the rest of the film's cast and the title were not yet finalised.

[10][11] The Telugu version's dialogues were written by lyricist Vennelakanti and the backdrop was altered to Kurnool instead of Madurai.

[12][13] In an interview to The Hindu, Karthik said that Jigarthanda was intended to be his directorial debut and that he incorporated some of his experiences in the film during his life at Madurai.

[14] In an interaction with IANS in early March 2014, Siddharth expressed his hope that Jigarthanda would help him break away from the stereotypical "boy-next-door" and "chocolate boy" roles he was known for, and allow him to showcase his versatility.

[17] It was reported in mid-July 2013 that Vijay Sethupathi would play the antagonist,[18] but soon after it was announced that he would do a cameo only if Karthik obliges as he had no dates.

[26] But director Karthik later informed the press that only 75% of the film's shoot had been wrapped up and while Siddharth had completed his part he may join during the patchwork left.

About the usage of Dolby Atmos for a small film which is also a romantic comedy, Karthik said, "Initially, I thought Jigarthanda would not involve as much work as Pizza.

He also introduced independent musicians, Pradeep Kumar, Sean Roldan, Anthony Daasan, Mani, Kalyani Nair to work with the film's soundtrack.

[33] The album features nine numbers of different genres, which includes fusion, folk and rap, with two instrumentals, one of them being performed by the composer's Sandy Jazz band.

A live band performance of Anthony Daasan took place and theatrical trailer of the film was screened at the event.

Producer Kathiresan, however, wanted a U certificate to avoid problems while selling the satellite rights of the film, for which the violent sequences were demanded to be cut short, which Karthik Subbaraj did not agree to.

[citation needed] M. Suganth of The Times of India gave 4 stars out of 5 and wrote, "If Pizza was a con movie dressed up as a haunted house horror thriller, Jigarthanda is basically a comedy cloaked as a gangster movie....[The] subversive streak is what makes this film singular and reinforces that Karthik Subbaraj as one of the exciting filmmakers of our time".

[48] Anupama Subramanian of the Deccan Chronicle gave 3.5 stars out of 5 and wrote, "Aided by his entire cast and technical department, breaking the myth that promising debut filmmakers may not fare in their next, Karthik Subbaraj clearly proves that he is here to stay".

[50] Haricharan Pudipeddi of IANS gave 3.5 stars out of 5 and wrote, "If the purpose of Jigarthanda was to deliver a tight slap on the face of the system, it has succeeded in it.

Thanks to the impeccable performances of the lead cast, especially Simha, director Subbaraj has conveniently conned us into seeing his film as a gangster flick-turned-comedy caper".

[54] In contrast, Gautaman Bhaskaran of the Hindustan Times gave the film 2 stars out of 5 and wrote, "If Subbaraj wanted to send a moral through his work – shed no blood – Jigarthanda flounders in a maze of 1960s kind of explanatory dialogues, and images that confound, and these despite fine performances by Simha (great expressions and body language) and Karunakaran as Karthik's sidekick.
