It was confirmed that Mohan Raja would direct the Tamil remake of Andhadhun, and that before working on the script, he had met Sriram Raghavan (director of the Hindi original) along with producer Thiagarajan. The most recent film to be headlined by Prashanth will be directed by JJ Fredrick of Ponmagal Vandhaal Fame. A source says, "A few things kept Raja up, and so, Thiagarajan approached Fredrick to direct the film." In reality, right after releasing his Ponmagal Vandhaal, Fredrick was approached. The team plans to begin shooting in Pondicherry starting in December.
It was learnt that one of the leads in the film may be Aishwarya Rai Bachchan. “The team approached her to portray Tabu's role. Soon, they will make the final announcements," the source adds. If this comes through, after their blockbuster, Jeans, Prashanth and Aishwarya will team up again. Although the original structure has been preserved, a few key portions have been modified. “The film is being re-enacted in different South Indian languages. So, for the roles, the team needs to cast the correct people", the source says, "Prashanth has lost oodles of weight and will be sporting a new look for the film."
