"I am overwhelmed by the great response the promo has got. This is just the beginning," Bhandarkar said in a statement.
Kareena plays Mahi Arora, an actress in the film, which narrates the ups and downs in the life of a movie star.
The trailer captures many facets of an actress' life - the struggle, success and downfall, and Kareena looks smashing in most scenes, including the item number Halkat jawaani.
Heroine, produced by UTV Motion Pictures, will release Sep 21.
