According to journalist Pat Jordan, when Peter Berg was researching "Battleship," he spent a few days on a Navy destroyer, and before he left, he made a short film for the captain and crew. The captain had earlier joked that Berg was a 'Hollywood lame ass" to ever think he could understand how the destroyer worked in only three days. Berg, in turn, joked that he could because he'd seen a lot of films, like Pearl Harbor (2001). To settle their 'argument', the two played the "Battleship" board game in front of the ship's crew while Berg sent a helicopter to film the action from above.

A Mustang is a term used for officers that are prior enlisted.

The other two were John Carter (2012) and Oliver Stone's _Savages_ and all three were box office disappointments (and, in the case of John Carter (2012), an unmitigated disaster). The failure of all three effectively stalled Kitsch's hopes of being the next big star.
