But the crew later opted for Asha Sarath, after watching her films.[23][24] Uma Riyaz Khan was signed for an "important role" [25] and Kishore informed that had been selected for a "key role" in the film.[26] In June 2015, it was reported that Madhu Shalini was part of the film and had starting filming,[27] while Sampath Raj was also added to the cast.[28] Sampath's character was revealed to be that of a local gangster called Pedha Babu.[20]

Following a photo shoot at the AVM Studios on 20 May 2015,[29] the film was officially unveiled on 25 May in Hyderabad with the release of the first look poster,[19] after which principal photography began with a schedule at the Ramoji Film City in Hyderabad.[30][31] The filming was completed in 38 days by August 2015.

Gautaman Bhaskaran of Hindustan Times gave the film a rating of 4/5 stars, calling it "an absolute slick crime adventure".[34] Latha Srinivasan of Daily News and Analysis gave 3.5/5 stars mentioning Thoongaa Vanam as a slick, well-made film that takes you through the course of happening over one night to the police officer and appreciated the debutant Rajesh M. Selva for directing a film that broke from the regular Kollywood films. They also appreciated the performance of Kamal Haasan, Trisha and music director Gibran for the excellent background score.[35] Avinash Gopinath of Filmibeat gave 3.5/5 stars and concluded "Without any songs and romantic sequences, Thoongaavanam [sic] is not your regular Tamil film. After all, who else other than Kamal Haasan can make a Kollywood flick look truly international?"[36]

Rating it 3/5 stars, S. Saraswathi of Rediff appreciated the performances of the lead cast as well as the film's technical aspects but criticised the lack of pace in the film's screenplay before concluding "the intriguing plot, good performances, Ghibran's innovative background score and camera angles of Sanu Varghese make director Rajesh M. Selva's Thoonga Vanam [sic] worth a watch."[37] M. Suganth of The Times of India also rated the film 3/5 and wrote, "even though the film cleverly spreads the action across various areas in the club [...] it isn't enough to shake off the feeling of claustrophobia. By the time the film gets over, we feel exhausted."[38] Entertainment website Behindwoods rated it 2.75/5, mentioning it as "There are thrills and surprises worth experiencing in this Thoongavanam", but also wrote "If one has to complain, it must be about the slightly slower pace of the movie", a contradictory statement when compared with general opinion. They appreciated the technicians as well as actors of the film with special mention to Trisha, and Aman Abdullah.[39] Karthik Keramalu of IBNLive gave 2.5/5 stars and wrote, "Actors move in and out of rooms, run this way and that, plot and fail, hide and seek. Yet all the effort of the cast and crew is shaken and not stirred enough as the screenplay gets a few nods wrong."[40]

Baradwaj Rangan of The Hindu stated that the film picks up in the post-interval portions "the kitchen-sink action choreography, the sounds of things breaking and clattering, the bursts of background score, the jittery camerawork", concluding the film as "an okay thriller", but criticised director Rajesh Selva for not giving the output to the dazzle of Brian De Palma films.[41] Sify described the film as a "classy thriller that gives an edge of the seat ride with world class action sequences and no-nonsense execution!". Kamal Haasan, Prakash Raj, Sampath Raj, Kishore and Trisha were appreciated for their performances, while they concluded mentioning about the technical aspects like music, action, editing and camera work that gave an edge to the film.[42] Raisa Nasreen of Bookmyshow termed the film as "A solid action-thriller".[43]

The Telugu version was released a week later with similar positive reviews. Sangeetha Devi Dundoo of The Hindu stated, 'though the film isn't really exceptional, makes for an engaging watch', appreciating director on the promising debut. She also mentioned the performance of Kamal Haasan, Prakash Raj and Trisha as good, concluding the film as a stylish cop drama as attention is paid even to little details of the film making.[44] Rating it 3/5 stars, Pravallika Anjuri of filmibeat stated that, even though the film is not up to the standard of an edgy or racy thriller, the performance of artistes, ideal run time and presentation makes it a must watch.[45] 123 Telugu gave the film a rating of 3.25/5 stars, calling it as a slick action thriller with interesting moments going on its way with a racy first half, concluding as the film is a must watch for those who like action thrillers and for the rest, the film is a decent watch.[46]
