Akshay Kumar is coming all out for his next project Blue. The movie Blue, will also be starring Sanjay Dutt, Lara Dutta, Zayed Khan, and Katrina Kaif. Each of them is shooting fairly strenuously as the project has already been floored. The movie will be based on the theme of Shipwreck and treasure, thus most of the shooting will take place under water. All the actors have been methodically trained in scuba diving in Bangkok.
