It’s official! After days of speculations, the makers of Tamil star Silambarasan TR’s next, tentatively called STR 49, confirmed on Wednesday (April 30) that actor Santhanam has joined the cast of the film.
Dawn Pictures, the banner backing the film, announced the news on their X handle.

The new film, directed by Ramkumar Balakrishnan, marks a reunion between Simbu and Santhanam after 2015’s Vaalu (the comedian had appeared in a cameo in 2016’s Idhu Namma Aalu).
Both actors have shared a cordial relationship over the years. Notably, Santhanam made his on-screen debut in Simbu’s Manmadhan, while the former’s Sakka Podu Podu Raja had music composed by STR.
STR 49, announced in February, has music composed by Sai Abhyankkar and features Kayadu Lohar of Dragon fame as the female lead. Details regarding the rest of the cast and crew are yet to be announced.
STR 49 will be produced by Aakash Baskaran of Dawn Pictures, who is backing Dhanush’s Idly Kadai and Sivakarthikeyan’s Parasakthi.
Meanwhile, Silambarasan’s 51st movie is with Dragon-maker Ashwath. Simbu, who is awaiting the release of Kamal Haasan-Mani Ratnam’s Thug Life, has teamed up with Desingh Periyasamy for his 50th film, tentatively called STR 50.
