Chennai: Director Ashwath Marimuthu has put an end to widespread speculation about his next directorial venture by officially confirming that his upcoming film will star Silambarasan TR. The project, tentatively titled STR51, marks the first collaboration between the Oh My Kadavule filmmaker and the popular Tamil star, and is expected to go on floors next year.
In recent weeks, Ashwath Marimuthu had generated considerable buzz online after reports suggested that he had narrated a script to Rajinikanth for the latter’s much-discussed project, tentatively referred to as Thalaivar173. The rumours sparked excitement among fans, with many speculating that Ashwath could be stepping into the big league with a superstar film. However, the director has now clarified that while discussions and speculation are part of the industry, his immediate focus is firmly on STR51 with Simbu.
Ashwath Marimuthu clarifies rumours around Thalaivar173
Ashwath Marimuthu addressed the speculation during a recent round-table interview with senior film journalist Sudhir Srinivasan, where he appeared alongside several other filmmakers. During the conversation, the director was candid about the constant questions he receives regarding his next project and the actor he will be working with.
“No matter who asks, the answer right now is the same — Simbu,” Ashwath said. He revealed that he is currently in the writing phase and actively developing the screenplay for STR51. According to him, the script demands focused preparation, and he wants to ensure that it lives up to both his creative standards and the expectations surrounding a Silambarasan TR film.
The director’s clarification has effectively cooled down speculation linking him to Rajinikanth’s next project. Thalaivar173 was initially announced with Sundar C at the helm, but the filmmaker opted out due to prior professional commitments. Since then, several names have been floated as potential directors, though no official confirmation has been made so far.
STR51 shooting and release plans
Ashwath Marimuthu also shared tentative timelines for STR51, offering fans a clearer picture of what to expect. He explained that Silambarasan TR is currently busy shooting for Arasan, directed by acclaimed filmmaker Vetrimaaran. Once that schedule nears completion, work on STR51 is expected to begin in parallel.
“He is shooting for Vetrimaaran sir’s Arasan, and towards the end of that schedule, we will begin filming our movie in parallel. It will be released next year,” Ashwath stated.
While the makers have not yet announced an official release date, industry sources suggest that the film is being planned as a 2026 release, depending on the scale of production and post-production requirements.
Genre and concept: A fantasy romantic action entertainer
STR51 is being described as a fantasy action romantic entertainer, a genre that Ashwath Marimuthu is keen to explore with Silambarasan TR. According to sources close to the project, Simbu will be seen in a larger-than-life role, with his character reportedly titled the “God of Love”.
The filmmaker has hinted that the film will carry the essence of vintage STR movies — blending romance, fantasy elements, humour and emotional depth. This approach is expected to resonate strongly with Simbu’s long-time fans, who have often expressed nostalgia for his earlier romantic entertainers.
Ashwath, who gained critical and commercial appreciation for Oh My Kadavule and later Dragon, is known for mixing high-concept ideas with relatable emotions. STR51 is expected to continue that trend, albeit on a grander canvas.
What’s happening with Thalaivar173?
Even as STR51 takes priority, interest around Thalaivar173 remains high. While there has been no official announcement from Rajinikanth’s camp, industry buzz suggests that Parking fame Ramkumar Balakrishnan could be in contention to direct the film. Interestingly, Ramkumar was earlier rumoured to collaborate with Silambarasan TR as well, adding another layer of intrigue to the ongoing speculation.
An official update on Thalaivar173 is expected around Pongal next year, a period when major Tamil film announcements are traditionally made.
Silambarasan TR’s busy work front
Silambarasan TR is currently immersed in the shooting of Arasan, directed by Vetrimaaran. The upcoming film is a gangster action drama and is being developed as a spin-off set in the Vada Chennai cinematic universe. Vetrimaaran has confirmed that several characters from Vada Chennai will appear in the project, making it one of the most anticipated Tamil films in the pipeline.
Arasan marks the first-ever collaboration between Simbu and Vetrimaaran, a pairing that has generated significant excitement among cinephiles. The film’s music and background score will be composed by Anirudh Ravichander, further raising expectations.
Apart from Arasan and STR51, Simbu is also said to be evaluating a few other scripts, though no additional projects have been officially announced yet.
Conclusion
With Ashwath Marimuthu officially confirming STR51 as his next film, clarity has finally emerged around the director’s immediate plans. The collaboration between Ashwath and Silambarasan TR promises a fresh yet familiar cinematic experience, blending fantasy, romance and action. While speculation around Rajinikanth’s Thalaivar173 continues, STR51 has firmly taken centre stage, setting the tone for what could be one of the most talked-about Tamil films of the coming year.
