Extra security on sets of 'Once Upon A Time In Mumbaai' sequel

The makers of the sequel to Once Upon A Time In Mumbaai have apparently employed a security agency in Oman to prevent the exclusive look of Akshay and other cast members including Imran Khan and Sonakshi Sinha from being leaked out.

The film is set in the '80s and every actor has a distinct look in the film. In fact, the makers have also banned cell phones on the film sets in Oman. Director Milan Luthria says, "We spent a lot of time and effort in coming up with these distinct looks for all the actors. I am getting a bit paranoid about protecting the exclusivity."
