Mumbai, Nov 5 (IANS) Ahead of the release of his new film '3 Idiots', Bollywood actor Aamir Khan Thursday drew a distinction between the term 'idiots' and 'stupid', saying that 'idiots are very normal persons' who at some point prove themselves in an 'unconventional way'.

At an event in a city hotel to promote the first song of Rajkumar Hirani's '3 idiots', Aamir said: 'Idiots are thought to be very normal persons but at some point of time they prove themselves to be someone with extra calibre. They are not stupid, rather they come to limelight in an unconventional way.'

Actor R. Madhavan and Sharman Joshi were also present at the screening of the song 'Jab life ho out of control, all is well'.

There are five songs in the film.

'3 idiots' is a story of three engineering students - Sharman Joshi, Aamir Khan and R. Madhavan - and their experiences on the campus.

Kareena Kapoor and Boman Irani play important roles and Kajol makes a special appearance in the film. The campus shown in the film is of the Indian Institute of Management-Ahmedabad (IIM-A).

The film is scheduled to release Dec 25.
