This film is from the last quarter of Raj Kapoor's career. He plays a voyeuristic private detective in the film paired with a relatively young Zeenat Aman. The film can be described as a caper comedy with elements of thriller mixed into it. As usual, the drama is elongated like in most Hindi films. What could be shown in hour and a half is stretched to over two.
Raj Kapoor had gained much weight at this time and hence, could hardly play the handsome hero ( like Dev Anand still did in the 80s ); hence settling for more suitable roles like this. His acting still has traces of Charles Chaplin in it and he pulls of his character brilliantly. Sadly, unlike films made under the RK banner of the 50s and 60s, this has a deplorable soundtrack. Raj Kapoor's 'voice', Mukesh, had died by this point and hence it was kinda weird listening to someone else lip sync to the Showman in this.
It's still an interesting film, the plot will keep you engaged even if it's a tad too long.
