Karthik Subbaraj's untitled project with Rajinikanth has got more stars joining the cast. On Wednesday, Sun Pictures, the producer, tweeted that Simran and Bollywood star Nawazuddin Siddiqui have agreed to be part of the film.

Earlier, it was rumoured that Karthik Subbaraj had approached Nawazuddin Siddiqui with the script but that the latter had not given him his nod. While Siddiqui is an established actor in Bollywood, known for her gritty roles, this will be his first Tamil film. He may have already become a familiar face to the southern audience through his recently released Netflix series Sacred Games in which he plays one of the main protagonists.

Vijay Sethupathi is also a part of this project, the details of which are still under wraps. Vijay Sethupathi signed up for the film in April and was the biggest name to join the cast after Rajinikanth.

This will be Simran's first collaboration with Rajinikanth. The actor recently made her comeback to cinema but hadn't quite managed to bag a substantial role. The Karthik Subbaraj film will hopefully land her more such projects.

Rajinikanth's Kaala hit the screens in June and the superstar is awaiting the release of Shankar's 2.0. Karthik Subbaraj's last film was the silent thriller Mercury and the young director has expressed his excitement about working with Rajinikanth. The superstar, after doing a slew of films with experienced directors, turned to fresher faces and younger filmmakers with Kabali. Unlike his contemporary Kamal Haasan who said that he will stop doing films shortly because of his plunge into politics, Rajinikanth has made no such announcement.
