Producer Poorna Chandra had been asking south Indian film director K Bhagyaraj (whose several south Indian films had been remade into Hindi films) to direct a Hindi film, after the producer persisting several times, K Bhagyaraj gave an outline first. Poorna Chandra liked the story so much that he wanted him to write a screenplay and give it to him. Initially the story was made into a Tamil film by Bharatiraja based on this script, Oru Kaithiyin Diary (1984) with Kamal Hassan. Poorna Chandra was adamant of making the Hindi version with Amitabh Bachchan. Amitabh was brought to Chennai for the story narration, he liked it. But was a little doubtful about the directors ability to direct an action film, as he had done only family oriented subjects, after some discussion Amitabh agreed and signed on.
When Vijay and IGP were watching the footage from the CCTV to prevent David from killing Dr. Varma, there was no audio from any of them. However, there was an audio from the two constables boasting that David will kill Dr. Varma even if Vijay and IGP made special arrangements made to prevent it from happening and that they will lose their jobs. So it's unrealistic how that audio was heard while the other screens did not have any audio at all.
