Following the release of Three Idiots, director Rajkumar Hirani frequently encountered people who shared how the movie inspired them to pursue their dreams. “I studied medicine but left it to learn music,” one person shared, while another admitted to chasing a writing career. These interactions sometimes left Hirani anxious, wondering if their efforts would succeed, fearing they might hold him accountable if they didn’t.
Hirani acknowledges that the film emboldened many to follow their passions. However, he emphasizes a crucial distinction between passion and obsession. “Passion is just a desire to be someone,” he explains. “What matters is obsession—whether you’re consistently putting in effort every day to refine your craft. Passion without effort won’t lead to success.”
Farhan’s Conversation with His Father

Hirani believes Three Idiots resonated deeply because it tackled the universal conflict between parents and children regarding education. Many parents, after watching the movie, admitted they might have been pressuring their children too much. The film highlighted the need for understanding and dialogue within families.
Hirani’s Own Story
Three Idiots is a film which has its roots deeply entrenched in the personal experiences of Hirani-the essayist himself. Recalling school days, he remembers as a normal student, struggling a bit with subjects like trigonometry. There was a determination to get into an engineering college; however, he couldn’t get in and had to study the commerce stream, which was not of much interest to him.
Then suddenly came the life-changing moment when he fell in love with theater. His father, who recognized this spark, encouraged him to take the unusual step of filmmaking-an unthinkable course for a middle-class family of Nagpur. Born of this, Hirani went on to film school, where he proved beyond doubt that it was indeed an aberration-leading to great success. It proved to him: “Pursue excellence and success will follow. Don’t chase money, as success doesn’t work that way.”
Crafting Memorable Characters

Boman Irani’s portrayal of Professor Viru Sahastrabuddhe was iconic, but the actor initially hesitated, concerned it might resemble his role in Munnabhai MBBS. Hirani reassured him by suggesting physical changes like curly hair and a mustache. Boman drew inspiration from his school teachers, even designing the character’s wardrobe and mannerisms.
Similarly, Rancho’s real name, Ranchhoddas Shamaldas Chanchad, was purposefully quirky to leave a lasting impression. Hirani and Abhijat Joshi brainstormed to ensure all characters had unique, memorable traits.
Casting Challenges
The original cast for the three main characters consisted of younger, lesser-known actors. However, their on-screen chemistry didn’t work as expected. Aamir Khan entered the picture when he expressed interest in the script, despite initial doubts about looking young enough for the role. After losing muscle gained for Ghajini, Aamir transformed into Rancho. To maintain believability, the supporting cast was also chosen to appear slightly older, ensuring a cohesive dynamic.
Sharman Joshi’s Home and Dark Humor

Hirani’s depiction of Sharman Joshi’s family home as a spoof of 1950s cinema was a nod to the era’s self-pity-filled storytelling. However, some viewers found the portrayal sensitive, prompting Hirani to reflect on the fine balance between humor and respect.
Ladakh Over Sikkim
The Delhi-to-Ladakh journey in Three Idiots was carefully planned to align with Rancho’s reclusive, knowledge-driven personality. Although Sikkim was initially considered, its distance from Delhi made Ladakh a more feasible option for the narrative.
Real-Life Inspiration for Kareena Kapoor’s Fiancé
The character of Kareena Kapoor’s materialistic fiancé was inspired by a real-life encounter with someone obsessed with brands. This stark contrast to Rancho’s values underscored the film’s theme of simplicity versus materialism.
