Some real, some fiction, ’18 Days’ is a movie based inside the submarine and it is being produced by PVP. Eighty percent of the shoot happens in a set built in Hyderabad whereas 20 percent is only computer graphics and that is being done in Vizag. They cannot shoot underwater because of the budget. It is a major highlight. The film is being directed by Sankalp Reddy who studied at the CVR College of Engineering and who did his masters in Fine Arts at Griffith Film School, Australia. This is the first submarine warfare movie and stars Rana Daggubati and Rahul Singh.
