Kareena Kapoor says she is not trying to copy anyone in her forthcoming film Heroine, the first trailer of which has raised inevitable comparisons with Vidya Balan's look in The Dirty Picture. In a way both films hit at the same subject - the fate, rise and fall of an actress. While Vidya scored a blockbuster with The Dirty Picture, Kareena and Heroine director Madhur Bhandarkar insist no comparisons must be made.

"I am not getting into anybody's shoes. I am very comfortable in my own and I would say that no one will get into mine either," Kareena said at the trailer launch held here Wednesday evening. She also said that Heroine has nothing similar to The Dirty Picture, and that it is "unfair" to compare the two.

Pointing out the difference between the two films, Bhandarkar said: "I liked 'The Dirty Picture'. The film was about the rise of an item girl in the 1980s. Our film is more modern in its approach. The two films are very different and you cannot compare them."

"There have been so many films based on underworld. Also so many cop films have come like 'Singham' and 'Dabangg', but no one compares them. Then why are people comparing these two films," he added. Produced by UTV Motion Pictures, Heroine, releasing Sep 21, also features Arjun Rampal.
