Cash-Cow Franchise: There have been countless variations of Battleship over the years, including a vaguely realistic fleet-based RTS (Simply packaged under the name Battleship), a vehicular combat game (Battleship: Surface Thunder), and the latest version of half Naval Ops, half Call of Duty (more of a tie in with the movie with little else in common with the classic game). The most popular remains "Two people with five ships shout/punch in numbers and reply with 'hit' or 'miss'," which also tends to come packaged (with minor variations) with many of the Battleship spinoffs.
Follow the Leader: Besides the original version, there's a lot of clones of this game, physical or computer versions.
Technology Marches On: There're versions out there where the aircraft carrier figure has an angled deck as modern ones and change the name of the ships -the battleship is now a cruiser, the cruiser a destroyer, and the destroyer a minesweeper/corvette-, as battleships are no longer in service in any navy.
The film:
Backed by the Pentagon: The film was shot on several US Navy warships, with active and retired military personnel both in front of and behind the camera.
Cast the Expert: Former Navy personnel who served on the USS Missouri were cast as extras in the film. However, the ship hasn't moved under its own power since its 1992 decommission.
Disabled Character, Disabled Actor: Gregory D. Gadson (who plays Lt. Colonel Mick Canales) had no acting experience prior and was cast due to being a double amputee combat veteran.
Fake American: Liam Neeson (Irish), Taylor Kitsch (Canadian), Alexander Skarsgard (Swedish), Rihanna (Barbadian), and John Tui (New Zealander).
Recursive Adaptation: The film adaptation of the board game was also turned into a board game.
