Boom is a Bollywood film that was released on 19 September 2003. It stars Amitabh Bachchan, Jackie Shroff, Gulshan Grover, Padma Lakshmi, Madhu Sapre, Katrina Kaif and Zeenat Aman. The film was a box office disaster and was panned by the critics. [ Contributing to its failure was the fact that the pirated copy of the movie was available in the market one full week before the release of the movie. The film is directed by Kaizad Gustad and produced by Jackie Shroffs wife, Ayesha Shroff.
The film explores the involvement of the fashion world with underworld crime.
Anu Gaekwad [Madhu Sapre], Sheila Bardez [Padma Lakshmi] and Rina Kaif [Katrina Kaif] are three of Indias top models. A prestigious diamond fashion show goes wrong, and inadvertently, they become embroiled in a jewelry heist. While on the runway, one of the models intentionally trips Anu - a models worst nightmare. Anus supportive friends, Sheila and Rina, come to the rescue. The trio confronts the model who tripped Anu and, soon thereafter, as the ladies get into a scuffle, they are met with a big surprise. Hundreds of glittering stolen diamonds, which were due to be smuggled out of the country, fall from the models hair and on to the runway only to be snatched up by paparazzi and celebrities alike.
Anu, Sheila and Rina are in shock as the fashion show turns to mayhem. The stolen diamonds are priceless antiques and have to be recovered by the gangsters, who hold the three glamorous models responsible for the heist-gone-wrong. The diamonds were due to be smuggled to Dubai and were stolen by Chhote Mia [Jackie Shroff]. They were then to be handed to his brothers .The leader of the trio, Bade Mia [Amitabh Bachchan] is determined to get the diamonds back and so begins a cat and mouse game between the three models and the three gangsters. Who will succeed in outwitting the others?
* This was Katrina Kaifs debut film. Producers were hesitant in casting Katrina in the film, because she could not speak Hindi.
