Let’s say you’re a film maker in the Hindi cinema of the late 1960s. You’ve set your heart on making a thriller. You have some money, but not enough to be able to hope to churn out something with Shammi Kapoor, set in Europe. You see all these glittering films—Teesri Manzil, An Evening in Paris, Jewel Thief—being released, and it irks you. If they can do it, why can’t you? So one day you gird up your loins, and inspired by all of these, and all the James Bond movies you can lay your hands upon, you set out to make your own thriller.
You cannot afford Shammi Kapoor [or is he perhaps too discerning to agree after he’s read the script?], so you settle for Biswajeet instead. You don’t have the budget to shoot abroad, but that doesn’t matter. You will make do by bringing abroad here to India, by plonking a bronze wig onto Biswajeet and having him pretend to be a Parisian named Robbie for much of the film.
