Professional photographers Vinod Chopra and Sudhir Mishra open a photo studio in the prestigious Haji Ali area in Bombay. After a disastrous start, they are given some work by Shobha Sen, the editor of Khabardar (transl.Beware, a pun on khabar meaning news), a publication that exposes the scandalous lives of the rich and the famous. Impressed with their work, Shobha hires them for a story about the connection between the Municipal Commissioner D'Mello and Tarneja, a builder. They find Tarneja and his business rival Ahuja working together to bribe D'Mello in order to win the contracts for construction of four fly-overs. Shobha asks the two photographers to create a rift between Tarneja and Ahuja. Vinod, impersonating Albert Pinto, leads Tarneja to believe that Ahuja, with Shobha's assistance, is trying to cheat him. Tarneja and Ahuja fight until Tarneja's secretary Priya arrives with Assistant Municipal Commissioner Srivastav and tells them that D'Mello has given the contracts to neither Tarneja nor Ahuja but to someone else.
Meanwhile, Sudhir and Vinod decide to enter a photography contest promising Rs. 5000/- and take a number of photos all over the city. In one of the photos, they see a man shooting someone and after enlarging it, they realize that the killer is Tarneja. They return to the park where they shot that photo and eventually find out the crime scene. They find the body lying behind the bushes but before the duo can get to the body, it disappears, but they manage to retrieve one of a pair of gold cuff links.
Sometime later, Srivastav has become the new commissioner. Tarneja has built a fly-over, dedicating it to the memory of late D'Mello, who he says died of a terminal disease. Vinod and Sudhir attend the inauguration of the fly-over and discover the other cuff link there. They return at night and dig up the area and unearth a coffin containing the dead body of D'Mello. They take several photos but lose the corpse again. Shobha starts blackmailing Tarneja with the photos. He invites her, Vinod and Sudhir for dinner and plants a time bomb to kill them. The bomb explodes after the three escape. They later find out from the news that the fly-over built in the memory of D'Mello collapsed and the police suspect sabotage from Vinod and Sudhir. The duo learn about Shobha's blackmail and disassociate from her.
Vinod and Sudhir find out that the body is with Ahuja who had, in an inebriated condition, carried the coffin to his farmhouse. They steal the corpse but not before Tarneja, Ahuja, Srivastav, Shobha and others also get involved resulting in a series of comic mix-ups.
Vinod and Sudhir present their evidence to the police. Tarneja threatens to take Ahuja, Shobha and Srivastav down with him. Srivastav brokers a deal between the four of them. He frames Vinod and Sudhir for the collapse of the bridge, jailing the two. In the final scene, Vinod and Sudhir are shown released from prison. Still in their prison clothes, they make a symbolic cut-throat gesture.
The film was not immediately successful at the box office when released, but was eventually regarded as a cult classic, which is reflected in a recent comment by Indian Express that the film's high recall value even after 37 years, is due to "it(s) superb satirical depiction of the essential, timeless, human condition: supreme self-interest versus some moral/ethical anchor. What made the depiction particularly powerful was its setting: India of the early '80s".[8]
Re-release
A digitally restored print of the film was released on 2 November 2012 at selected theaters.[9] The film opened to an enthusiastic welcome from the media.[10][11]
Blow-Up, a 1966 English-language film directed by Michelangelo Antonioni in which a photographer believes he may have witnessed a murder and unwittingly takes photographs of the killing, was an inspiration for Jaane Bhi Do Yaaro.[13][14] The filmmakers paid homage to Blow-Up by naming the park in which the murder occurs "Antonioni Park".
The names of the lead characters – Vinod Chopra and Sudhir Mishra – came from film directors Vidhu Vinod Chopra and Sudhir Mishra, who were assisting Kundan Shah in the movie.[15] Sudhir Mishra co-wrote the script and assisted in directing the movie, while Vidhu Vinod Chopra was the production controller of the film.
Vidhu Vinod Chopra played Dushasana in the Mahabharata play in the climax of the movie. He also played a photographer in the first half of the film, where a group of journalists interviews Tarneja, played by Pankaj Kapoor.
