Courtroom scenes were once a favorite genre during the Golden Era of Bollywood. Of late this is completely missing in our films, barring one or two exceptions like Jolly LLB or Pink.
The reason I think for creating a courtroom scene, a solid script is required, a lot of groundwork, understanding of law and procedures of a court, and finally a perfect direction.
In the 1950s and 1960s, the court scenes usually come at the fag end of the film. Most of these scenes foretold by a quick shot of the national slogan "Satyamev Jayate" or by the shot of Goddess of Justice wearing a black colored bandage on the eyes and carrying a pair of weighing scale on the hand and almost invariably, the truth did prevail.
Each decade presented a peculiar legal drama, in the late 40e patriotic court cases were common, recall the court scene of Shaheed (!949), where Dilip Kumar is being prosecuted. In another film Amar (1954).Dilip Kumar plays the role of an advocate. There was a court scene where Dilip Kumar fights a case for Madhubala.
Dev Anand films had many courtroom scenes. every fourth film of his had a court scene, either he is a lawyer or a convict. In Paying Guest he plays the role of an advocate. Similarly in 1962 film Baat Ek Raat Ki, he once again played a lawyer. In Kala Bazar there was a famous court scene in which Chetan Anand appeared. as a lawyer. In the 1968 film Dev Anand once again played the role of an advocate.
In the 1951 film Awaea, in a very famous court scene, Nargis appeared as an advocate for the convict Raj Kapoor.
Without a doubt, the courtroom scenes played out by stalwarts Ashok Kumar and Motilal are the highlights of the film. In every scene, one tries to be up on the other and both are an absolute treat to watch. Without these two superb artistes and the riveting courtroom performances, this film would have been hollow. As it is, there are too many empty spaces when Dutt and Naidu are in the same frame.
Sunil Dutt plays the defense advocate and acts his heart out, complete with long emotional gazes and melting puppy eyes in a bid to engage the conscience of witnesses. During one cross-questioning, he engages in an entire spectrum of emotions. From screaming at a witness, he moves close and almost whispers to him, urging him to place his hand on the Bhagwad Gita and reverse his earlier statement. Further, in order to prove a point about footprints at the crime scene, he actually drags a sack dripping with red liquid into the courtroom and asks the prosecutor to enact it himself.
Andha Kanoon released in 1983 was a film about law and justice. The film takes a shot at how manipulative could be the law. Jan Nisar Akhtar Khan (Amitabh Bachchan) is charged with killing Ram Gupta (Amrish Puri), , tried in Court, and sentenced to 20 years in prison. Years later, an angry and embittered Khan is released from prison. Khan finds out that Gupta is still alive and decides to kill him, quite dramatically in the same courtroom where he was convicted for his murder.
