This film’s positives are the great songs by Shankar-Jaikishan, the choreography, the filmi noir set decoration, and the Helen-Pran chemistry. Gumnaam is familiar to western audiences because the film Ghost World used its first song (“Jaan Pehchaan Ho”) in a scene. This song kicks off the journey into a crazy world where bouffant hair meets men in dresses; giant Easter Island statues with glowing red eyes compete with Helen for your attention; and a killer on the loose stalks his terrified victims. The drawbacks include a patchy and nonsensical plot, and Nanda and Manoj Kumar as the lead pair (Shammi and Asha Parekh would have been so much better!), but this is nitpicking when compared to the pluses.
