It is well documented that Suriya left a film with Sudha Kongara, Purananooru, which the filmmaker later revived with Sivakarthikeyan and has since been titled Parasakthi. Recently, the filmmaker talked about why Suriya left the project, Purananooru. In a conversation with Behindwoods TV, the director said that she discussed the idea of the film with Mathimaran, her close friend who once served as an assistant director under Vetri Maaran, during the COVID pandemic period. Then, the director said, she narrated the story to Suriya, and he was "very excited" about doing it. Sudha Kongara does not know the exact reason for Suriya's exit from the film, but she singled out a big stumbling block for the project. "One major problem was the lack of time to shoot continuously for the film. If we had not shot this film continuously, economies would not work and the production team could not have taken that expense," Sudha Kongara explained.
Sudha also talked about casting Sivakarthikeyan in the lead role. The filmmaker said that Sivakarthikeyan's close friend Arun Viswa asked her many times about whether she had any project in mind for the actor and that she kept saying no to him for a while. Eventually, upon Arun's persistence, the filmmaker agreed to propose a love story to Sivakarthikeyan and met the Amaran star at a screening of Kottukkaali, which the actor produced under his namesake banner. "I narrated a part of the story to him, he liked it very much and agreed to do the project." The filmmaker added that the actor loved the screenplay and his character and okayed the film without even looking at the bound script.
Parasakthi is releasing in theatres on January 10, a day after Vijay-H Vinoth's Jana Nayagan.
