The plot, if you didn’t know, goes thus: Thakur Baldev Singh (Sanjeev Kumar) of Ramgarh hires two small-time crooks, Veeru and Jai (Dharam and AB), to capture dreaded dacoit Gabbar Singh (Amjad Khan), the man who murdered his entire family. The novelty lies in how the tale’s told. Salim-Javed’s legendary screenplay is packed with innumerable subplots, digressions, comic skits and three long flashbacks. In fact, it’s structured like a series of small films. So you remember each scene distinctly; whether it’s Asrani’s the Great Dictator spoof or a drunk Veeru atop a water tank declaring his love for Basanti. And yet all these sequences coalesce into a perfect whole. The spectacular, long opening scene of a dacoit attack on a running train remains the most kinetic opening in Indian cinema.
