Writer Jaideep Sahni got the idea for the script when he was flicking through a newspaper and a small story about a women's hockey team caught his eye.
When Kabir Khan takes his crew to give a farewell lunch, they end up fighting with a group of anti-social elements, in the fiasco one of the girl pushes a guy off the bar and he falls on a car breaking its windshield. Later on in a long shot at the end of the scene, one can see the car intact.
When Komal Chautala arrives, she is seen playing hockey with the boys. In one shot they are shown swerving their hockey stick around a man and she hits the ball. In the next shot the ball breaks a mirror on the driver's side of the car and the same man is sitting on the driver's side of the car.
Kabir Khan: This is the story of a team and they're playing for their one and only dream. To win the world cup so you better back up. Cause they're coming on now and they're coming on how. Get out of the way cause they're screaming "Chak De"!
