Sriram Raghavan says he is working on the script of his next film and will most probably make an announcement by next week.
"I am scripting my next film right now. It is a thriller. I can't disclose anything more about it as of now. We will be making the official announcement by next week or so," Raghavan, whose last venture was Saif Ali Khan-Kareena Kapoor-starrer Agent Vinod, said.
He hopes to complete the final draft of the script by December and said: "It is too early to think about the cast as of now. We will be locking the script by December and then we will think about the cast."
The yet-to-be-titled movie is slated for a 2013 release.
Raghavan earlier directed Johnny Gaddaar and Ek Hasina Thi.
