Director Mari Selvaraj made his debut with Kathir and Anandhi with Pariyerum Perumal, which received a lot of appreciation from critics and audience alike. Pariyerum Perumal managed to impress not just Tamil audience but also people from other states. After Dhanush watched Pariyerum Perumal, he was mighty impressed with director Mari Selvaraj. He was so impressed with the filmmaker that he immediately signed a film with him. The film, which will explore the struggle of a person in a village, is titled Karnan.
After wrapping up the film, Karnan is currently in the post-production stage. While doing re-recording for the film, composer Santhosh Narayanan watched the film and appreciated the makers. He wrote, "Watched #Karnan. Stunned! Proud of you @dhanushkraja sir, @mari_selvaraj, @theVcreations and the wonderful team (sic)." When Mari Selvaraj completed the shoot, he wrote on Twitter, "Karnan shoot completed. Thank you Mari Selvaraj for giving me this. Thank you The VCreations Thanu sir for the support. Sincere thanks to all my co-stars and technicians. A special thanks to Santhosh for the overwhelming music you have given for this special film."
