"Let's groove for the celebrations of a lifetime," wrote Mythri Movie Makers, unveiling the promotional song 'Thandanaanandha' made for 'Ante Sundaraniki'. The June 10th release has Nani and Nazriya in the lead. Shot on them and the artists who have played their parents in the Vivek Athreya directorial, the promo song is peppy.

Sung by Shankar Mahadevan and Swetha Mohan, the jamboree song has background vocals by Gomathi Iyer, Sree Poornima, and Snigdha Sharma. Ramajogaya Sastry has penned the lines. "The song is as much fun as the film is," the 'Shyam Singha Roy' actor tweeted, plugging the Vivek Sagar composition. The deployment of the Nadaswaram and the Violin is winsome. Nani is in his elements, so also the 'Raja Rani actress, for whom 'AS' is a Telugu debut.

The film will be released in Telugu, Malayalam, and Tamil on the same day, that is, June 10. Naresh, Rohini, Nadhiya, Harshavardhan, Rahul Ramakrishna and Suhas have supporting roles. The film has cinematography helmed by Niketh Bommi and editing by Raviteja Girijala.
