Silambarasan has joined hands with Parking fame Ramkumar Balakrishnan for his 49th film. The poster of the yet-to-be-titled film was unveiled on Monday, on the occasion of the actor's birthday.

Aakash Baskaran of Dawn Pictures, who is backing Dhanush's Idly Kadai and Sivakarthikeyan's Parasakthi, is the producer for STR49 as well. While plot details are under wraps, the first-look poster features Silambarasan holding an engineering book as well as a bloodied butcher's knife, suggesting that the actor could be playing a character leading a double life—one as an engineering student and the other as a murderer.

Meanwhile, Silambarasan also has an upcoming film with director Ashwath Marimuthu. Production of the untitled film is scheduled to begin after Ashwath's Dragon, starring Pradeep Ranganathan, is released on February 21. Silambarasan recently wrapped shooting for Thug Life and also has an upcoming film helmed by Desingh Periyasamy, in the pipeline.
