Talaash, slated to release on November 30, also stars Rani Mukherji, Kareena Kapoor and Nawazzudin Siddiqui in pivotal roles. Aamir is playing a cop for the third time in the film after 'Baazi' and 'Sarfarosh'.

There were reports that Aamir and Kagti had differences over some scenes that he wanted re-shot but both of them have denied it.

Kagti, who made her debut with 'Honeymoon Travels Pvt Ltd', admits that the actor was very involved with the project but without interfering with her vision.

"The kind of enthusiasm and sincerity that he shows are that of a first timer. He is very involved and really obsessed with getting the best possible thing for a product. He puts in a lot of effort and I could see that he took a lot of trouble to understand what I was trying to do on the film," Kagti said.

"What is really notable about him is that even though he had a lot of inputs, he was honest to my vision and went along with that," she said, quashing reports of any differences with her lead actor. 'Talaash' will be Aamir's first release since '3 Idiots' and the actor is leaving no stone unturned to create a positive buzz for the film. Kagti, on her part, says things became easy for her once he agreed to do the project.

"I had heard that Aamir brings a lot on the table and I experienced that first hand during the making of 'Talaash'. His coming onboard proved to be a huge green light for the project because the moment someone like him gives a go ahead, it is easy to crew up and cast your film," Kagti said.

The director is convinced about the final product that is ready to roll on screen but says it is not a fast paced thriller.

"Talaash is not a fast paced thriller. Instead, it is a gripping suspense story which is taken forward by a very powerful starcast.
