who knew how to get out of chakravyuh
Padmavyuha The Chakravyūha or Padmavyūha was a very special formation (vyuha), and knowledge of how to penetrate it was limited to only a handful of warriors on the Pandavas' side, namely: Abhimanyu, Arjuna, Krishna and Pradyumna, of which only Abhimanyu was present when the Kauravas used it on the battlefield. In the Mahabharata it is mentioned that Abhimanyu learnt about the Chakravyūha while in his mother's womb but he was not able to hear how to escape the formation. After Abhimanyu had penetrated the sixth tier of the formation, all the Kauravas' commanders attacked him simultaneously, which was against the righteous rules of warfare Dharmayuddha, and gradually exhausted and killed him.[2]
Gabbar Singh (character) Danny Denzongpa was the first choice of Gabbar but had to miss out because he was shooting for Dharmatma in Afghanistan.[9] Amjad Khan was almost dropped from the project because Javed Akhtar found his voice too weak for Gabbar Singh's role but was later convinced. For his preparation for the role Amjad read Abhishapth Chambal, a book on Chambal dacoits written by Taroon Kumar Bhaduri (actress Jaya Bhaduri's father).[10] Sanjeev Kumar also wanted to play the role of Gabbar Singh, but Salim-Javed "felt he had the audience’s sympathy through roles he’d done before; Gabbar had to be completely hateful."[11]
