In the 60s Kishore Kumar had a remarkable stint as an actor and worked in a number of reasonably successful movies that blended his comic flair and good songs to provide a safe bet for the producer. Mr. X in Bombay released in 1964 and was directed by Shantilal Soni starring Kishore Kumar, Kumkum and Madan Puri in principal roles.
The movie has a bit of science fiction as we see a scientist creating a potion that leads to a death. Then there is a love story between the scientist’s daughter and the hero. Hero is eliminated by the villain, but hero returns and gets the heroine and the villain is punished. How does all this happen?? Watch the movie 🙂 There is an invisibility potion in the movie 🙂 that plays a key role 🙂
