"Battleship" is Hollywood's latest movie about the military that includes some real-life heroes. It is loosely based on the 1967 board game Battleship, which later became a video game.The film was shot on several ships based in San Diego, including the USS Ronald Reagan, USS Bonhomme Richard, USS John Paul Jones and the USS Sampson."It adds credence to the movie," said Sgt. Miriam Gelo, an Air Force Medical Technician.Sgt. Robert Holland, who also an Air Force Medical Tecnician, added, "It's not all CGI. There's some authenticity to it."A military expert told 10News the movie was likely heavily vetted through the Pentagon and may be a thinly veiled attempt to recruit young gamers into the military.Holland does not think so."I think they're just trying to put a movie out there so people will go to it," he said. "It looks fun and entertaining. I don't think there's any type of hidden agenda."The movie studio allowed members of the military around the world to see an advance screening of the movie. One man said, "Just saw the movie 'Battleship' here in Japan. I thought it was just going to be another sci-fi flick. All I can say is 'WOW'! As for the non-'alien' parts it was almost like being back on active duty again."The movie opens on Friday.
