As Tamil cinema modernized, the "420" trope shifted from simple comedy tracks into standalone thriller films. A prime example is the action drama .

Later in 1973, Haasan appeared in another Balachander directorial, Sollathaan Ninaikkiren (transl. "I am trying to say"). Though his role was relatively small compared to what would come, the film itself was significant. Based on Manian's novel Ilavu Kaatha Kili , the movie starred S. V. Subbaiah, Sivakumar, Srividya, and Jayasudha in lead roles. Haasan's presence in even minor roles during this period demonstrated Balachander's commitment to nurturing him.

In the last five years, creators have taken the audio from these vintage films and mashed them with modern beats. Specifically, the "Nadodigal" conversation scene from Panchathanthiram (the "Pathu Kaasu" dialogue) has been remixed thousands of times under the #Tamil420 hashtag.

Section 420 of the Indian Penal Code deals with cheating and dishonestly inducing delivery of property. The punishment can extend to seven years of imprisonment and a fine. Over time, "420" entered colloquial vocabulary as a term for a con artist or someone who cheats others.
