When I watched the 1949 Nishaan last week on Youtube, the topmost recommendation in the side panel was what was billed as another copy of the same film. Just for the heck of it, I clicked on the link, and arrived at a completely different film: Nishaan, yes; but a Nishaan made 16 years after the 1949 one, and a Nishaan too which is important for one major reason: it marks Sanjeev Kumar’s debut in a lead role (and that too a double role).
Sanjeev Kumar had already played small parts in two films—Hum Hindustani and Aao Pyaar Karein, but this film, with ‘Introducing Sanjeev Kumar’, was his first big role(s). He didn’t soar to success immediately, and most of his films over the next couple of years were fairly forgettable (as Nishaan is, to some extent). But despite the general unimpressiveness of this film, what stands out is the very natural acting of its leading man.
