Actor-writer Zeishan Quadri, who co-wrote and played the role of 'Definite' in 'Gangs of Wasseypur', said he regrets not asking for royalty for the film. Zeishan added, "I said if I'll write the script, I'll also act in it...I thought that was a smart move." "But had I written that script today, I would've demanded royalty in...contract," he said.
