With less than a month to go for the release of Dhanush's much-anticipated Idli Kadai, the makers have been unveiling character posters from the film every day. While Arun Vijay will be playing Ashwin in the film, Sathyaraj will take on the role of Vishnu Vardhan, which many speculate to be Arun Vijay's father character. On Monday, it was announced that Rajkiran will be portraying Sivanesan in Idli Kadai, a key role linked to the beginning of Dhanush's Sivanesan Idli Kadai. Dhanush is expected to either inherit Sivanesan's modest restaurant or begin the shop in his honour.

Apart from Dhanush, Arun Vijay, Sathyaraj and Rajkiran, the cast of Idli Kadai, includes Nithya Menen as the female lead, Samuthirakani, with Parthiban making a cameo appearance in the film. Idli Kadai is set to release in theatres on October 1.

The film is produced by Akash Bhaskaran through his Dawn Pictures banner and Dhanush through his Wunderbar Pictures banner. Inban Udhayanidhi, son of Tamil Nadu's Deputy Chief Minister Udhayanidhi Stalin, is set to make his debut as a film distributor via this film.
