Multiple sets in the movie were made from scratch by the skilled crew. The entire alien mothership interior, the science nerd (Karuna) and the other friends' (Ragu, Vasu, Thiruna, Mani) rooms were all artificial and not actual terrace apartments, the mess hall on the ground floor was also entirely made from scratch and later repurposed into a realistic underground sewer line for the final scenes in the movie.
The science nerd Karuna was played by the first grandson (Bijesh Nagesh) of legendary Tamil cinema legend C.K. Nagesh.
One of the friends, Mani, was played by Abu, who is Rowther's son and heir to the production company that made this movie. In fact, several scenes in the film were shot inside, atop, and under the same building where the film's company offices stand.
This was Tamil actor/hero Aari Arjunan's much-awaited movie, which saw a few unforeseen production delays. During this time, Aari went on to win the prestigious Big Boss Tamil title in the year 2021.
This is U. Kaviraj's directorial debut. The TV-movie was released/broadcast on the same channel (Colors Tamil) where Mr. Kaviraj started his career. This film, therefore, marks a full-circle moment, memory, and milestone for him.
