If industry sources are to be believed, the box-office success of Hrithik Roshan and Katrina Kaif-starrer 'Bang Bang' last year has spurred the makers to come up with a sequel to the action flick. Sources say the script is currently being worked upon and the lead actor is likely to be retained in part deux. However, it is not yet clear if Katrina will be paired opposite Hrithik again.

Says an insider, "The film was among the top grossers of 2014 and buoyed by its success, the producers have already started work on the second instalment of 'Bang Bang'."

A source close to the makers confirms the development, saying: "We are trying to come up with a script that can match the standards of the first part. Though it's early to comment, it looks like the project will go on floors next year. We are not sure if Siddharth Anand will direct the film, but Hrithik is definitely being considered for the sequel. As far as the actress is concerned, we might either sign Katrina or settle for a fresh face. Wait for an official announcement."

After 'Bang Bang' released in October last year, the director had hinted about a sequel. The spokesperson of the film studio, which had backed the film, remained unavailable for comment.
