The film, directed by debutante Neeraj Pandey, releases on September 5.

In the film, Shah plays a terrorist who will not stop at anything while Kher plays the role of a police commissioner who has to stop the terrorist at all costs, Pandey said.

Shah and Kher began their careers in almost the same decade, where Naseeruddin became an actor to reckon with after Nishant in 1975 but Kher took couple of years to make it to the marquee with Saransh in 1984.

Both eyed the same kind of roles and there was almost a healthy rivalry among the friends. They both acted together Jaane Bhi Do Yaaro (1983) but Kher's entire track was deleted, and the film went on to become a cult for Shah.

Finally after 19 years, both of them have liked a script together. In fact one of the main factors for both of them to come together was because the 'other' was working on it.

"It was great working with him; we worked together in few films like Pestonjee, Misaal, Tridev. When I signed the film, I was unaware of the rest of the cast, so when I came to know that Naseerji is also a part of the film, I was really thrilled and was looking forward to work with him," Anupam Kher said.

Kher and Shah came together in Subhash Ghai's Karma (1986), followed by Pestonjee (1988), Tridev (1989), Chaahat and China Gate.

With over 146 films, Shah become the messiah for parallel cinema with landmark films like Manthan, Bhumika, Akrosh, Bazaar, Mandi, Jaane Bhi Do Yaroon very early on in his career. He also tried his hand at some popular cinema with films like Masoom, Umrao Jaan, Sarforsh but his heart remained in roles with an edge.
