Southern actor Ram Charan is working hard to perfect his Hindi diction for his Bollywood debut, while Priyanka is trying to get a grip on the southern diction.
While they are both trying to help each other, a source says that post pack-up, both the actors spend two to three hours brushing up their dialogue delivery.
The source says members of the film's crew have laid a bet of Rs.500 on the two actors, as who would forget their dialogues first.
This fun game has been instrumental in helping them deliver their dialogues perfectly as the two superstars have taken it up as a task and keep pulling each other's leg on the matter.
Co-produced by Reliance Entertainment, Amit Mehra and Flying Turtle Films, "Zanjeer" will release in summer 2013.
