Kangana Ranaut's Simran and Apurva Asrani's script: A comparison

What the script also explores is Praful's frustration at not being able to raise the money to pay back the loan. She begs friends and relatives and no one helps her. At one point, she also tries to steal from her father, after which she loses her head at the gas station and decides to rob the first bank. In the film, the bank robbery happens without exploring Praful's state of mind deeply.

In the script, the Praful researches the robberies properly. She only goes to banks where the crowd is thin, or she chooses a time when the change of the guard happens, and there is a 15-minute gap in the security. The Atlanta Police also exist in the screenplay, and at one point, Praful is chased by a police vehicle, but manages to give them the slip. And because her car may have been identified, she goes to a pound and has the vehicle destroyed.
What we see onscreen was not exactly this. There are montages of shots where Praful checks out a bank before entering, but there is no detailed research that goes into planning the robberies. In the film, the robberies add to film's comic flavour and not its heft. Also the police are practically non-existent till the climax.
