Filmmaker Madhur Bhndarkar asserts that Kareena Kapoor's performance in his latest project "Heroine" is not only fabulous, it will also be a shocker for her fans.

"Her character Mahi Arora is very contemporary, very edgy, very hard-hitting and very real like my other cinema.

Kareena will definitely be a shock element to the people because of the way she has worked in the film, " the 43-year-old producer-director said here at the launch of photographer Dabboo Ratnani's calendar.

"I am looking at the film because I know the story, I know the screenplay, I know the dialogues. She will be fabulous, " he added.

Known for his films like "Chandni Bar", "Satta", "Page 3", "Traffic Signal" and "Fashion", Bhandarkar believes "Heroine" will be a milestone in Kareena's career.

" 'Heroine' is 25 percent over. The next schedule is in February, March and April and the picture will release in September. The way you people are waiting for the film, so am I. I hope it finishes really soon, " he said.

The director found himself in a tight spot when Aishwarya Rai, the original choice for the film, decided to quit the project due to her pregnancy.

Kareena is also expected to tie the knot with Saif Ali Khan early this year and the actress may wrap the film up before that.
