Plot: Two friends are searching for their long lost companion. They revisit their college days and recall the memories of their friend who inspired them to think differently, even as the rest of the world called them "idiots".
The college and the hostel scenes were filmed at Indian Institute of Management, Bangalore
Aamir Khan never stands still in the entire movie. He is always swaying in some direction. Apparently, he concluded that the the new generation of kids never stand still after observing his nephew.
Aamir Khan's character Rancho says in the movie that people study engineering, then management, and then become bankers, so what is the whole point of studying engineering. This is exactly what Chetan Bhagat (the author of 'Five Point Someone', the book from which the movie has been adapted) did. He studied engineering from IIT, management from IIM, and became a banker.
While shooting the drunk scene, Aamir Khan suggested that they get really drunk.
Shahrukh khan was offered the role of Rancho but he declined.
When Virus asked students who wants to win the pen in the first day of school, Rancho is the only character who didn't move his hand.
It is based on the novel Five Point Someone by Chetan Bhagat.
This film was remade in Tamil as Nanban (2012)
In January 2016, director Rajkumar Hirani and actor Aamir Khan confirmed that they were considering a 3 Idiots sequel.
Author Chetan Bhagat who wrote the book on which the film was based criticized the film-makers for trying to hide his involvement and not giving him proper credit for the film. According to him he was misled into thinking that the film was based on an original idea and was very loosely "inspired" by his book "Five Point Someone". However after the movie was released he was shocked to see that the movie resembled the book very closely but he was not given credit in the film and the story was credited to Rajkumar Hirani and Abhijat Joshi.
According to Chetan Bhagat he was pressurized to remove his "Based on a novel by Chetan Bhagat" that is displayed in the film to a more generic "Initiated by a novel by Chetan Bhagat" but he refused since the film-makers did not give him a copy of the script.
Chetan was paid 10 Lakh rupees by the film-makers to acquire the rights to his novel.
