Naach is an artistic romantic drama movie made by Ram Gopal Varma (RGV), and it flopped at the box office. Abhishek plays the role of a struggling actor, and Antra Mali plays the role a struggling choreographer with new ideas. The story is about giving chances to new ideas instead of following the established formula of success. I think that the story is inspired from the career of RGV where he has been giving chances to new talents with both success and failure. In the meanwhile, other movie makers have made movies based on established clichés and success formulas. Anyhow, these comments can also be regarded as speculations.
Naach is a nice movie, but maybe too artistic. That was probably the reason for why it didn’t work commercially.
