Now a film that shows the bad effects of the paparazzi hounding celebrities, which is dime a dozen. Remember Princess Diana. All right, Showbiz has that touch with reality, but the script is too weak for a three-hour-long film. The script is just unable to carry the whole content for that prolonged period.
The plot is sketchy; it hovers somewhere between a hatred of the media and love for well, politicians. Every celebrity is a politician. The film desperately tries to tell that the media has ruined many a good lives of famous people by ruining their otherwise decent celebrity status. Good point, but yes, also a bad point, because the story doesn’t tell that – it only tries.  Perhaps the only relief is in watching this film with Mahesh Bhatt in mind. This for some reasons: the subject is new, director Raju Khan is a debutant, and debutant casts Tushar Jalota and Mrinalini Sharma may offer some something.
The protagonist Rohan Arya is a sort of a celebrity who has the dough and influence and things like that. But he’s also chased by the paparazzi everywhere he put his feet, which annoys the hell out of him. 
One night this guy takes a prostitute in his car, and to his luck, the paparazzi follows him in what looked like a Need for Speed Underground car chase.
Then his car gets all worked up after an accident and the prostitute finds herself in the hospital. Rohan tries to explain things to the public, but in vain, because the media twisted his story like his mangled car.
So the car crash was just a decoy by Mahesh Bhatt; the script boils down to how the media hounds the life out of Rohan for better circulation, revenue and TRPs.
But even reality is doubtful here (Bhatt should have double checked): paparazzi is not the media; they are freelance folks who sell for money to the media. The bottomline is anybody can watch this film, but it’s not worth seating for three hours. The same material can be had from Wikipedia’s entry of Princess Diana. Also, if one is bad and five is excellent, Showbiz gets two, including songs, direction and the technicals.
