After giving many power-packed performances in her decade-long career, Bollywood superstar Kareena Kapoor admits she follows her director's advice religiously on the sets. Kareena, 32, was here to launch the worldwide trailer of Prakash Jha's Satyagraha, in which she plays a headstrong journalist. "We are familiar with popular women journalists on TV like Barkha Dutt and Christiane Amanpour. Their personalities influence everyone and I am lucky that I have also got the chance to essay the role of a journalist on screen. But ultimately I am a director's actor and don't really believe in preparing much; I followed whatever Prakashji wanted from my character. I have always wanted to work in a Prakash Jha film," she said.

The film also stars Ajay Devgn, Amitabh Bachchan and Manoj Bajpai. Satyagraha centres around the recent phenomenon of mass movements around the world, challenging the establishment and thereby making a change. Devgn, who is on a family holiday here, said the film is an entertaining one and engages the audience thoroughly. "All that it points out is that if you want change, you have to make it happen yourself. But it is basically an entertainer. The audience don't want to be educated through films, they want to be entertained. And, Prakash Jha is a filmmaker who has managed to strike that golden balance of engaging with the audience and saying what he wants to say at the same time," said Devgn.
