Nenjil Thunivirundhal

Kumar (Sundeep Kishan) (Surya in Telugu version) is a somewhat timid young man who, after losing his father to a negligent operation, takes care of his mother (Thulasi) and medical student sister Anuradha (Shathiga) by running a catering outfit. His best friend is Mahesh (Vikranth) who likes talking with his fists and the comedy duo (Soori) and (Appukutty) (in Telugu played by Satya). Mahesh and Anu are secretly in love, and they hide it from Kumar / Surya as it would spoil their friendship. Durai Pandi / Sambasivudu (Harish Uthaman) is an assassin whose modus operandi is to double-cross his clients and earn double the money for his kills. Ensuing circumstances seemingly make Mahesh the target of Durai Pandi / Sambasivudu. However, there is a twist there, and whether the good guys and their dear ones survive against the powerful and ruthless enemy forms the rest of the screenplay.

In November 2016, Suseenthiran began working on an untitled film as director with Sundeep Kishan and Vikranth signed on to play lead roles. Initial reports suggested that the film would be a bilingual Tamil and Telugu venture, where Kishan would replace Vikranth in the Telugu version, but later both were included in the cast.[6] Vikranth worked on the film alongside his commitments in Suseethiran's production venture Vennila Kabaddi Kuzhu 2 (2017) and Samuthirakani's action drama Thondan (2017). Harish Uthaman and Soori also joined the cast in November 2016.[7] Sundeep Kishan reunited with Suseenthiran after a previous venture, the Telugu version of Jeeva (2014), had been shelved midst production.[8] Actress Mehreen Pirzada was brought in to make her acting debut in Tamil films, and recruited a Tamil instructor to help her learn the language. Production began in December and the film was shot across Chennai, Vishakapatnam, Nellore and Tirupathi.[9] The film's initial title, Aram Seidhu Pazhagu, and first look poster were revealed to the media on 14 February 2017. When the title was changed to Nenjil Thunivirundhal, the team again released the first look with the new title.[10][11] The team has wrapped up the filming in June 2017.[12]

When speaking about the heroine's role in the film, the director Suseenthiran said, "usually my scripts will have importance for the role of female leads, but in this particular movie, Mehreen Pirzada is having a cliché role". Despite being a bilingual, the entire film in two languages was shot in 55 days.[13]

The film's music was composed by D. Imman, while the audio rights of the film were acquired by Saregama. The album released on 5 October 2017 and featured five songs and two theme tracks.

The makers originally planned to release the film in early October 2017 to coincide with Diwali, but postponed the release owing to the lack of available screens.

The Tamil version of the film opened to mixed reviews from critics on 10 November 2017. A critic from The Hindu wrote that Suseenthiran "is out-of-form in this action drama", while The New Indian Express wrote that the film was an "uninspired thriller" and that it "pretends to be an enterprising thriller, but what it actually is, is your garden-variety cliché-ridden film.[14][15] In a more positive review, The Indian Express wrote the "movie is an average thriller". Sify.com called the film "entertaining", explaining that "the movie has a charming friendship angle, middle-class family issues, a social message and a deadly villain".[16][17] Baradwaj Rangan of Film Companion wrote "The premise is similar to what the director handled to far better effect in Naan Mahaan Alla and Pandiya Naadu, where ordinary men found themselves in extraordinary circumstances. The story has terrific potential. (It’s the tragedy with so many of our films: great story, lousy screenplay.) "[18]

The film garnered a poor commercial response at the Chennai box office, owing to the unexpected success of Aramm, which was released on the same day. Coupled with the success of the horror film Aval and Mersal, Nenjil Thunivirundhal underperformed commercially.[19] Within four days of the release of the film, Suseenthiran re-edited and trimmed nearly 20 minutes of the film to re-release, with many scenes featuring Mehreen Pirzada being removed.[20] As the new version failed to get an immediate positive response, Suseenthiran chose to pull the film from the theatres on 16 November 2017 and later announced that there would be a re-release on 15 December 2017. Owing to the busy schedule at the box office, the idea was later scrapped, meaning that the film only ran for six days in Chennai.[21]
