A day after Kadaisi Ulaga Por's theatrical release, the film's makers released 'Arasiyal Undertaker' on Saturday.

The song composed and written by Hiphop Tamizha Adhi is sung by him and VM Mahalingam. The number is a theme song for 'Natty' Natraj's character, who claims to be a kingmaker and a political powerbroker.

The film that was released on Friday opened to mixed responses from the audience and critics. The CE review of the film reads, "The film constantly manages to make you laugh and keep you entertained. Initially, you would expect the film to offer a heavy dose of political sermons with a side of science fiction. While it did offer these things, the film's action and thriller portions turned out to be the most entertaining."

The cast of Kadaisi Ulaga Por also includes Natty, Anagha, N Alagan Perumal, Harish Uthaman, Munishkanth, Singampuli, Kalyan Master, Elango Kumaravel, Thalaivasal Vijay, Mahanadi Shankar, Elango Kumanan, Vinoth GD, and Guhan Prakash, among others.

The technical crew of the film includes cinematographer Arjun Raja, editor Pradeep E Ragav, art director RK Nagu, and stunt director Mahesh Mathews.
