"I have not finalised her (Deepika) yet but we would love to work with her. I have just met her and sounded her idea," Radghavan told PTI.
"She (Deepika) is a talented actress and we would like to work with her. But till I don't finish my script I can't talk about it (casting)," he said.
When asked whether Deepika liked the idea, Raghavan said, "She is aware about the book.
She has read the book but the book and movie are two different things. Once my script is ready then I will talk about casting."
However, the 'Badlapur' helmer has not thought of casting other actors for the film. "I don't think we will go with newcomers not for a main role. I think we will go with a star as that is the requirement," he added.
The 'Johnny Gaddar' director is yet to finish writing. "I am still not fully ready with the script. I had told them (producers) by end of June., that I will finish it but I haven't. We are yet to cast anyone for the film ," he added.
According to him, changing a novel into a film is a bit easy.
"The good thing is the story is already there... characters are fetched out. It is not like starting all fresh.
After that it is a matter of structuring. It is easier to adapt than write your own story."
Once Raghavan is done with script he would show it to its author.
"That is a later stage discussion as I can talk about it once I am ready with the script. Once I am done with writing the script then I have to meet the author take his feedback and then I can talk about it in detail."
Meanwhile, Deepika is busy shooting for Sanjay Leela Bhansali's "Bajirao Mastani".
