Kamal Hassan and A R Rahman collaborates for the magnum opus 'Thalaivan Irrukindraan'.

Actor-filmmaker-politician Kamal Haasan is gearing for his next film, Thalaivan Irukkindraan, a project that was announced way back in 2008. Pre-production works continued throughout late 2008, with actors such as Rishi Kapoor, Mohanlal and Venkatesh approached for leading roles. But the project was put on hold citing financial issues.

Later it was revived in 2015 and announced that the film will be made in Hindi as well and will be titled, Amar Hain. While Haasan will play the antagonist, Saif Ali Khan was supposed to play the main lead. Haasan was supposed to return to Bollywood with this project after 18 years and he had planned to write and direct the project.
