Nadaga Sabha play of the same name. It was he who, in 1950, gave Ganesan a flight ticket to Madras for the screen test for Parasakthi. Ganesan had simultaneously shot for the Telugu-Tamil bilingual film Paradesi / Poongothai, which was supposed to be his actual film to release first, but released much later after Perumal requested its co-producer Anjali Devi to let Parasakthi release first. Ganesan had earlier dubbed for actor Mukkamala in the 1951 Tamil film Niraparadhi. Parasakthi did not begin well for Ganesan. When shooting began and 2000 feet of the film was shot, Meiyappan was dissatisfied with Ganesan's "thin" physique, and wanted him replaced with K. R. Ramasamy. Perumal refused, and Ganesan was retained. Meiyappan was also satisfied with the final results of the film. The initial scenes of Ganesan which he earlier disliked were reshot.

Rajagopalachari, E. V. Ramasamy, M. Bhaktavatsalam, Annadurai, and Karunanidhi. Although Ganesan began working on the film in mid-1950, it took over two years to complete. Themes Panju stated that Parasakthi was designed to "create havoc. Of course, it did. We were challenging the social law itself, the basic Constitution itself". The title song of the film was composed by Bharathidasan, keeping with the demand of the DMK party seeking a sovereign Dravidian nation. The poem glorifies the utopian nature of the Dravidian
