By now its common knowledge that Aamir Khan is a perfectionist to the core. The cast and crew of 3 Idiots got a first hand experience of this during the shooting of the film. For a particular scene in the film, the trio of Aamir Khan, Sharman Joshi and R. Madhavan had to be shown drunk. It was a night shoot and Aamir suggested that they actually get drunk to make it look more authentic. Poor Sharman and Maddy had no choice but to listen to their senior co-star.
Soon the trio started drinking and within few minutes were in their element completely. Director Rajkumar Hirani was happy with the way actors were giving their takes and wanted to shoot various options to choose the best. After taking a few retakes, the unit realized that they had run out of reel in the middle of night. When Raju Hirani got to know about it, he was worried because he didn't want this shoot to extend for another day and didn't want the cast to get drunk again.
The production team went all out hunting for the reel to check if any other film was being shot in the vicinity and if they could borrow some reels from them. Fortunately for them, there was a regional film being shot and the director of the film was more than happy to help Rajkumar Hirani with reels. Finally the team managed to get a reel to wrap up the shoot. After this interesting incident they surely much have said 'Aal Izz Well that ends well'.
