3 idiots is the drama movie, there are main characters . it is a movie about 3 idiots in their college life. in college, farhan and raju from a great bond with rancho due to his refreshing outlook. years later, a bet gives them a chance to look for their long lost friend whose existence seems rather elusive. the casts are aamir khan, kareena kapoor, sharman joshi, r.mahadavan, and boman irani, omi vaidya moa singh, etc. . it is the one of my favorite movie.every one should watch
