Anurag Kashyap says he will only stop working with frequent collaborator Nawazuddin Siddiqui when they will not have anything new to offer to the audiences. Siddiqui has featured in Kashyap's Black Friday and Dev D but it was the Gangs of Wasseypur series, headlined by the actor, which brought him the long overdue recognition.

The duo have also worked on Raman Raghav 2.0 and now Kashyap has shot portions featuring Siddiqui for the latest Netflix original Sacred Games. In an interview with PTI, Kashyap says much of his process is "discovering something new" and if he is uncomfortable, he will not resort to repetition - neither of himself nor his favourite actor.
