Saif Ali Khan-Kareena starrer spy film, 'Agent Vinod' may not have created a stir at the box office, but director Sriram Raghavan is upbeat on making a sequel.

Earlier, even before the movie got released, Saif had said he would make it into a franchise.

"We are toying with some ideas for the sequel but we haven't started writing the script yet. But there are a few ideas. As 'Agent Vinod' is still running in theatres, we would wait for 15 days or so and then begin our work (scripting)," Sriram.

The action-spy film, directed by Sriram released on March 23. Asked if he would repeat the lead pair in the sequel, Sriram said, "Saif would be there in the second instalment as 'Agent Vinod'. The story would move to different places but eventually India would also be part of the plot. It would be like the Bond series."

"Other characters would change. Also, once we finish writing the script we would think of which characters to retain and which not," he said. Also, the director has learnt his lessons.

"We have got a good response. The area where we need to improve is length. As it is a fast-action-spy movie, we need to reduce its length. In the next series, we would make sure the length is of two hours only," Sriram said.
