28 years after Arunachalam, director Sundar C and Rajinikanth are set to collaborate for a new film. According to reports, Rajinikanth is expected to complete a film before he joins the sets of the much-awaited project with Kamal Haasan as the film's director and script are yet to be finalised.

Speculations are rife that this yet-to-be-confirmed film will begin immediately after the completion of Nelson Dilipkumar's Jailer 2, which is slated to hit theatres on June 12 next year.

Sundar C is currently busy with the production of Mookuthi Amman 2, starring Nayanthara who is returning as the titular Amman (Goddess) in the lead. Regina Cassandra, Suneel, Yogi Babu, Abhinaya, Duniya Vijay, Ineya, Garuda Raam, Singampuli, Vichu Vishwanath, Ajay Ghosh, and Myna Nandhini, among others are also part of the film. The upcoming film is backed by Ishari Ganesh of Vels Films International and will also be co-produced by Sundar C-Khushbu Sundar's Avni Cinemax Pvt Limited, Nayanthara-Vignesh Shivan's Rowdy Pictures, and Ivy Entertainment.

Rajinikanth, meanwhile, was last seen in Lokesh Kanagaraj's Coolie. Rajinikanth and Kamal Haasan's reunion was announced at a star-studded event recently, with Lokesh Kanagaraj speculated to direct, but the actor confirmed that the director, along with the script are yet to be finalised. "I am doing a film for Raaj Kamal Films International and Red Giant Movies with Kamal Haasan. However, the director for the film, the storyline, and our characters are yet to be finalised. I hope this film materialises, but it all depends upon the story and the director," he said.

Arunachalam, written by Crazy Mohan and directed by Sundar C, starred Rajinikanth as the title character as well as in a dual role, alongside Soundarya and Rambha, with Jaishankar, Ravichandran and Visu in supporting roles. The film was a box office success and is considered a classic in Rajinikanth's filmography, widely appreciated for its story, screenplay and music.
