Hindi cinema of the 50s and 60s was all about producing grand heroes and ferocious villains. The mightier the bad guy, the greater is the good guy’s triumph. And we had many contenders for villainy, since the real estate occupied by villains at the time on movie posters was as much as that of a hero. A villain, once established had a long innings —easily 30-40 years, which is more than heroes can speak of—this increased shelf life allows them to move from villain to a character role, or that of a close friend or comrade, to comedy, and then eventually to father/father-in-law roles. Starting from KN Singh, and moving to Rehman, Pran, Jeevan, Prem Chopra, Madan Puri, Ajit, Ranjit, the 50s to the 70s were the era of the villain.
