Krazzy 4 is a crazy story of four crazy people. These people are staying at a mental rehabilitation centre. The roles are played by well known Arshad Warsi, Irfan Khan, Rajpal Yadav and Suresh Menon. Arshad Warsi is not really crazy; he is there to get a hold of his temper that he loses immediately. Suresh Menon does not speak at all though there is no problem with his vocal cords and he is not mute. Rajpal Yadav is a patriot who is stuck in the Gandhi era and Irfan Khan is a doctor who is obsessed with the cleanliness thing. The cast also includes Juhi Chawla who is a doctor to the four at the rehabilitation centre. She takes them out to show them a match but when she leaves them in the car to get something from the office, she gets kidnapped. The four of them set on to find her. The story takes a turn when they find out that she has been kidnapped by her own husband. The mp3 songs of the movie are good and the song lyrics have been written by well known Asif Ali Baig and Javed Akhter. Over all the movie is a good time pass.
