Close on the heels of the release of Amaran, the makers of the film, starring Sivakarthikeyan and Sai Pallavi in lead roles have released another single. Titled 'Uyirey', the song has been sung by Nakul Abhyankar and Ramya Bhatt Abhyankar with lyrics by Vivek.

Earlier, the makers had released 'Hey Minnale', and 'Vennilavu Saaral'. 'Hey Minnale' has been trending on all social media platforms since its release and has also entered the international Billboard charts.

The film is based on the life of Major Mukund Varadarajan (Sivakarthikeyan), and is directed by Rajkumar Periasamy. Amaran also stars Bhuvan Arora, Rahul Bose, Lallu, Shreekumar, Shyam Mohan, Ajaey Naga Raaman, Mir Salman and Gaurav Venkatesh.

Major Mukund Varadarajan was a commissioned officer in the Indian Army's Rajput Regiment. He was posthumously awarded the Ashok Chakra for his act of bravery during a counterterrorism operation while on deputation to the 44th Rashtriya Rifles battalion in Jammu and Kashmir. 

Amaran's crew includes music composer GV Prakash Kumar, cinematographer CH Sai, editor Kalaivanan, and stunt director Stefan Richter. The film is bankrolled by Kamal Haasan's Raaj Kamal Films International along with Sony Pictures International Productions.
