Actor-director Parthiban, who last made Teenz in 2024, revealed that he is playing a cameo role in Dhanush's upcoming film Idly Kadai. Taking to his X handle, he shared a photo with Dhanush and expressed his happiness on being able to work with the actor after two missed opportunities.

"After missing out on acting in Aadukalam, a film that deserved another National Award, and after Soodhadi, which we began together but didn’t take off, it felt like things had come full circle when he personally invited me to play a small honorary role in Idly Kadai. I accepted without hesitation. The dubbing was completed yesterday," he wrote.

The filmmaker also heaped praise on Dhanush, calling him a multi-talented artist and a pan-Indian star who "sparkled" in the film which he witnessed first hand.

Apart from Dhanush and Parthiban, the film also features an ensemble cast consisting of Arun Vijay, Nithya Menen, Rajkiran and Samuthirakani, among others. While it is hinted that Dhanush will take on the role of the owner of a modest eatery called Sivanesan Idli Kadai, much of the details surrounding the plot are unknown.

On the technical team, Idly Kadai has music by GV Prakash Kumar, who is reuniting with Dhanush after Nilavukku En Mel Ennadi Kobam, Vaathi and Captain Miller. It has cinematography by Kiran Koushik, editing by Prasanna GK, and production design by Jacki. The film is Dhanush's fourth directorial after Pa Paandi, Raayan, and Nilavukku En Mel Ennadi Kobam.

Idly Kadai is made collaboratively by Dawn Pictures, Red Giant Movies, and Wunderbar Films. Aakash Baskaran and Dhanush are the producers, while Sreyas Srinivasan is the executive producer. The film hits theatres on October 1.
