Chekka Chivantha Vaanam is an upcoming Indian Tamil-language crime thriller film co-written and directed by Mani Ratnam. The film features Aravind Swami, Vijay Sethupathi, Jyothika, Silambarasan, Arun Vijay, Aishwarya Rajesh, Dayana Erappa and Aditi Rao Hydari as the ensemble cast, while Prakash Raj, Jayasudha, Thiagarajan and Mansoor Ali Khan appear in pivotal roles.

The venture is jointly produced by Mani Ratnam and Subaskaran under their banners Madras Talkies and Lyca Productions, the music is composed by A. R. Rahman, while Santosh Sivan is the cinematographer and Sreekar Prasad is the editor.

The principal photography commenced on 12 February 2018 at the outskirts of Chennai and got completed by 2 June 2018 at Serbia. The film is releasing worldwide on 27 September 2018 along with its dubbed Telugu version Nawab.

Following a brief break after the release of Kaatru Veliyidai (2017), Ratnam chose to begin pre-production on his next film by June 2017 and brought in composer A. R. Rahman and cinematographer Santosh Sivan for the project.

In July 2017, reports in the media suggested that Mani Ratnam's next film would feature four lead male characters and actors Vijay Sethupathi, Arvind Swami, Fahadh Faasil and Dulquer Salmaan were in negotiations to play various roles. While the first three actors eventually accepted to work on the film, discussions with Dulquer fell through. Silambarasan later signed the film in early September 2017, and an official announcement from the production studio confirmed the four lead actors were attached to the project. Telugu actor Nani had also held discussions with Mani Ratnam for a role in the film, but was later not included in the final cast. Prior to the beginning of the shoot, Silambarasan undertook a rigorous weight loss regime to get into shape for his character. In the months leading up to the start of the shoot, there was speculation in the media that Silambarasan would be banned from the project after allegations were made by producer Michael Rayappan about the actor's deliberate lack of co-operation during the making of Anbanavan Asaradhavan Adangadhavan (2017). Despite protests from other film producers, Mani Ratnam chose to retain Silambarasan in the film. In a media interaction during January 2018, Vijay Sethupathi confirmed that he would portray a full length role, denying reports which suggested that he had an extended cameo appearance. Fahadh later opted out due to scheduling conflicts with other projects. He was replaced by Arun Vijay.

Jyothika agreed to portray a leading female role in early September 2017, and confirmed her participation to the media while promoting Magalir Mattum (2017). She had earlier appeared in Mani Ratnam's production venture Dumm Dumm Dumm (2001), but stated her excitement at being selected in a film to be directed by him. Likewise, Aishwarya Rajesh also revealed her presence in the project during early September 2017, and expressed her delight working with Mani Ratnam. In late January 2018, Aditi Rao Hydari, who had appeared as the lead actress of Mani Ratnam's previous project Kaatru Veliyidai (2017), was also confirmed to be a part of the cast. Model Dayana Erappa also later joined the cast to play the fourth leading actress, marking her first acting assignment. She was cast after two rounds of auditions and then prepared for her role by attending workshops led by theater actors in Mumbai.

For a supporting role, actress Jayasudha agreed to work on the film in November 2017, while Prakash Raj joined the cast during the following month to portray her husband. The production house revealed that actors Thiagarajan and Mansoor Ali Khan were also added to the cast before filming started. Furthermore, other supporting actors including Cheenu Mohan and Malayalam actor Antony Varghese were reported to have signed to play characters in the film, though Varghese was later replaced by Appani Sarath. Chennai-based radio jockey Sindhu also debuted as an actress, during the first schedule. Siva Ananth was credited as the co-writer, while Bejoy Nambiar worked as one of the creative producers. Dhilip Subbarayan was signed to choreograph the stunt sequences, while Sharmishta Roy and Eka Lakhani were signed as the production designer and costume designer, respectively.

A. R. Rahman began composing on the film on a recce to Goa with Mani Ratnam and lyricist Vairamuthu. The album was released on 5 September 2018 by Sony Music, and Rahman gave a live performance of the songs.
