Sakalakala Vallavan () previously known as Appatakkar () is a 2015 Indian Tamil-language romantic action comedy film written and directed by Suraj. The film stars Ravi Mohan (credited as Jayam Ravi), Trisha Krishnan and Anjali, while Prabhu, Soori and Vivek appear in supporting roles. S. Thaman composed the film's music, while cinematography was by U. K. Senthil Kumar and editing by Selva RK. The film was released on 31 July 2015, and failed at the box office.
Shakthi and Chinnasamy are family enemies who fight over an election. During that time, Anjali falls in love with Shakthi, whom he later discovers is Chinnasamy's cousin. Shakthi is forced to marry Divya under some circumstances. Before starting a life together, Divya tells Shakthi that they must get to know each other, but every time Shakthi tries to do something good, it ends bad. Divya asks for divorce and Shakthi tells Divya to stay for a month with his parents so that they will not get hurt over the fact that they made Shakthi marry someone who does not like him. To make this worse, Shakthi's father gets Divya to stand for the female election, to which she agrees. When she loses the election, Shakthi's father hits him. That is when Shakthi reveals how he lost in love and life. Seeing how much he loves and respects his family and how his life has been, Divya slowly starts to like Shakthi. At the end, Divya and Shakthi happily live together while they argue over little things, making their life filled with love, and with a lesson from Chinnasamy saying that couples' fights are for fun, and no one else should get involved in them.
The film was launched in early June 2014 as a collaboration between director Suraj and producers Lakshmi Movie Makers with Jayam Ravi signed on to play the leading role. Actress Anjali was signed on to play a female lead role in the same month, marking her comeback after a hiatus from Tamil films. Suraj later revealed that Dhanush was the original choice for Ravi's role. The team began shooting in Chennai in July 2014. A set resembling a Tenkasi market and costing was erected for this schedule.
Trisha joined the cast in August 2014 to play another female lead, after the team opted against signing Kajal Aggarwal, who had asked for a high remuneration. Vivek did a role in the film for which he shaved his head. The film was initially titled Appatakkar, after a line popularised by Santhanam in Boss Engira Bhaskaran. In July 2015, the title was changed to Sakalakala Vallavan after M. Saravanan, the producer of the 1982 film of the same name, gave the makers permission to re-use his film's title.
S. Thaman composed the soundtrack of this film.
The Hindu wrote, "For a film that tries to be a comedy, Sakalakala Vallavan makes for a sombre experience". Rediff.com rated 1 out of 5 and said "The absurd script, inept execution, bizarre antics of the lead and supporting actors coupled with some ordinary music make director SurajâÂÂs Sakalakala Vallavan Appatakkar a total bore". The Times of India rated 0.5 out of 5 and noted that "Sakalakala Vallavan is so abominable â a blot in the career of everyone involved in making it â that it makes us question its very existence and how it even came to be made".
