Adding to the crowded office of Mahesh Bhatt [Images] in Mumbai's Juhu-Vile Parle area are the directors and actors of his latest film, Killer. One of them, actor Irrfan Khan [Images], spoke to rediff.com about his latest project and forthcoming work. Excerpts:

"I am not an authority on the film, so I cannot tell you much about it. It's more fun to watch a film than to hear about it. Films are meant to be understood and experienced. Killer is like a roller-coaster ride -- an intense film. It is like a Tom and Jerry film where the two characters, Emraan and I, try to get the better of each other.

I prepare differently for every movie. It depends on the situation as well as the character, and my experiences in real life. I play a freelancer in this film; one who does a job for whoever pays me.

Mira Nair's Namesake, in which I have played a part, will be released worldwide in November by Fox Searchlight.

I entered the world of cinema because of Naseerudin Shah. He has influenced an entire generation. He is an innovative actor and has made realism popular. Motilal and Dilip Kumar [Images] used to do it earlier, but Naseer has laid more emphasis on it. It is not method acting or instinct, it is more than that. He has introduced acting as a craft to us.

I don't do every role offered to me. I don't do all kinds of characters. I have three or four releases a year. How can you do more than that? Many filmmakers do not choose me, and I am also choosy. Yu Hota To Kya Hota, directed by Naseerudin Shah, is another of my forthcoming releases, apart from Killer.

I have acted in one film with Shobhana. It has yet to be titled, but it has been shot. It is about bringing up a child. I have also worked on another film called Tulsi, with Manisha.

There are a few directors I would love to work with, and Sreeram Raghavan is one of them. I want to work with Naseer again, and with Vishal (Bhardwaj, who directed him in Maqbool). Mani Ratnam is very good, as is Ram Gopal Varma. I loved Taxi No 9211. Anurag (Bose, who made Gangster [Images]) is another good director.

I am doing a film with Sunny Deol and another one called Thevar. For the moment, I am only doing Hindi movies."
