In July 2012, it was reported first that Suriya had signed on Lingusamy\\\'s film to be produced under the director\\\'s banner and that he would work on it after Maattrraan and Hari\\\'s Singam 2. After the completion of both films, the actor was reported to work simultaneously with Lingusamy and director Gautham Menon for a film titled Dhruva Natchathiram.In September 2013, many sources incorrectly stated that the film was titled Rowdy, however the director denied these as rumors.Suriya reportedly waited for six months after the release of Singam 2, but failed to receive a complete script from Gautham Menon and no progress took place in this period of time. Owing to this reason, he opted out of Gautham\\\'s film in October 2013 and announced that he would soon start work on Lingusamy\\\'s film.The director confirmed the news and also stated the film would officially start filming from mid-November 2013. It was said that the script had been modified a few times.The film was started without a title. In January 2014, the title was officially announced to be Anjaan.
Vijay Milton was first roped in by Lingusamy as the cinematographer for the film,but in October 2013 he was replaced with Santosh Sivan, who worked for the first time with Lingusamy. In mid-October, a test shoot occurred with Suriya and Malavika Rampradeep, a Bharatanatyam dancer, with the Red Dragon Digital camera along with a high zoom lens. It was reported that it was the first film in the world to be shot with the camera. The technology had not even been used in Hollywood films, according to the makers.
The film\\\'s editing was reported to be handled by Anthony while Rajeevan was roped in as the art director. Brinda Sarathy will be working as dialogue writer for the film. Suriya was said to possess two different appearances for filming, starting with a raw and jagged look. In early November, Manoj Bajpai was reported to be playing the film\\\'s antagonist while Vidyut Jamwal would also appear in a prominent role. Dalip Tahil was signed for the role of a small, but powerful don in the film.Comedian Vivek was approached to play a role in the film,but could not take up the offer as a result of date clashes with Vai Raja Vai. Instead in March 2014, another comedian Soori was signed. Sana Khan was approached to do a special number in the film but she declined the offer as she wanted to promote her Bollywood film Jai Ho.
Filming started on 20 November in Mumbai. A few days before it began, Suriya completed a photo-shoot of the film which was done by still photographer Venkatram. The lead actors were shooting in Mumbai, but came back to Chennai before the one-month schedule.In December 2013 the intro song was filmed with Suriya, Vidyut Jamwal and Maryam Zakaria. The song, described as a \\\"peppy number\\\", was shot in a set, worth 80 lakhs, that had been erected in Borivali in Mumbai. The first schedule was wrapped in early January 2014. In early February 2014, the crew was shooting for a song sequence in Panchgani. The third schedule started on 5 March 2014 in Mumbai.A further item number was shot with Manoj Bajpai and Chitrangada Singh in March 2014, after discussions to have Sonakshi Sinha in the song were unsuccessful.
