"Agent Vinod", an action spy thriller has got a U/A certificate from the censor board after a screening Wednesday and Saif Ali Khan is happy with this.

Directed by Sriram Raghavan, the film has Saif in the title role and is releasing March 23. Kareena Kapoor plays the female lead in it.

"Our film has a lot of action but we have worked on keeping it more realistic and less violent. And after censor board's screening, we have got a U/A certificate and I am very happy," said the actor who is in the city for the film's promotion.

"We wanted more people and even the kids to watch the film. And my son Ibrahim is also very excited and told me that he and his friends want to watch 'Agent Vinod'," added the actor. Perfect for sequels

Saif Ali Khan also feels that his upcoming action-thriller 'Agent Vinod' with Kareena Kapoor has the potential to become a successful franchise

Though the actor says it is too early to talk about sequels, he admits that the idea has crossed his mind. "I want to take one step at a time. If the audience like the film and they want more, we would go forward with it. I think the film is perfect for a franchise but it is too early to talk about it," Saif told in an interview.

"The film has taken about three years. I got lots of bumps and bruises along the way but it was worth it because I felt it could be something. If it becomes a franchise, it would be a dream project," he added.

Saif, 41, has produced the film through his Illuminati Films banner besides playing the central character of a RAW agent in the movie, which hits screens on March 23. It has been directed by Sriram Raghavan, who gave Saif his career's first negative role in 'Ekk Hasina Thi'.

"That film was a little ahead of its time but 'Agent Vinod' is releasing on the right time. Sriram Raghvan is a very interesting director and he has done something remarkable in this film too," said Saif. The film's song Pungi... is already on its way to become one of the biggest hits of the year.

The actor says he contributed a lot to the peppy dance number. "There is a sequence in the film when Agent Vinod is being watched in a close circuit camera. We wanted to show the audience that Agent Vinod is capable of humour. People may think that he is a copy of James Bond but he is very Indian. Pungi is a lovely song. I made half of the steps myself. It was good fun."
