After it was recently announced that Shanmuga Pandian and Thiru's upcoming film was titled Vaanavedikai, the makers updated that Shivani Rajashekar has joined the cast. Composer Sam CS has been attached to this upcoming film.

Vaanavedikai marks Shivani's third Tamil film after Anbarivu and Nenjuku Needhi (both in 2022). Daughter of legendary actor Rajashekar and sister of actor Shivathmika, Shivani was last seen in the Telugu romantic comedy, Vidya Vasula Aham (2024), opposite Rahul Vijay.
