Known for directing films like "David" and "Shaitan", the director hasn't titled his film yet.
"I am still writing my next film and not decided about the cast yet. I am still working on the script and don't want to comment on it. I just met him (Aditya) once and we are talking. I don't want to reveal anything more than that," Nambiar told IANS.
"Once I finish the script, I can probably talk about it but right now it's too early," he added.
Reportedly the untitled film is the same project that Nambiar was supposed to do with Shahid Kapoor.
