The trailer of Rana Daggubati's Ghazi, touted to be India’s first submarine-based war movie, is already trending on the social sites. It looks like the film will truly be a visual brilliance on screen. This Telugu-Hindi bilingual will be dubbed in Tamil as Madai Thirandhu. It is based on the real incident of the mysterious sinking of PNS Ghazi, a Pakistan submarine, during the Indo-Pak 1971 war. Directed by Sankalp and produced by PVP Cinemas, Taapsee is the leading lady and the film is on its verge of completion. The film has cleared the censors with an U certificate and will hit the screens on Feb 17.
