Rajkumar Hirani's 3 Idiots starring Aamir Khan, Kareena Kapoor, Sharman Joshi, Madhavan and Boman Irani has gone on floors. The film is a feel good family entertainer. It has the same warmth, simplicity and fun associated with Raju Hirani's films.

Hirani doesn't want to give away the look of his protagonists right now, which is why the teaser doesn't have any of the actors in it.

The shoot of the film with the supporting characters has already begun. Hirani and his team will be leaving in late August for the shoot with the principal cast.

The film is scheduled to be shot in Ladakh, Delhi, Bangalore and Mumbai as well. Aamir and rest of the cast will begin shooting in early September. Hirani plans to wrap 3 Idiots by December.

Vidhu Vinod Chopra is producing the film. Abhijat Joshi and Raju Hirani have written the screenplay and the lyrics are by Swanand Kirkire. Shantanu Moitra is composing the music for the film.
