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.
Referenced by...: Toy Story: One of the presents that Andy receives for his birthday is the Battleship board game. In a later scene, Hamm and Mr. Potato Head are seen playing Battleship, with the former winning against the latter.
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.
If Unit:E had managed to launch, the crew of the ISN Everest from the Battleship Galaxies game would've fought alongside many other Hasbro heroes.
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.
A downplayed case for Taylor Kitsch. Despite his career in harm's way by the failures of this movie, John Carter, andSavages, he managed to snag a supporting role in the well-received Lone Survivor a year later. He still manages to find film and TV work such as the second season of True Detective, American Assassin, Waco, 21 Bridges, and The Terminal List, but more of a supporting player and less of a main lead. At the very least, his performances in the aforementioned projects have been met with slightly more praise.
Any chance Brooklyn Decker had at becoming a movie star was ended by this movie and Just Go with It. She now sticks to her modeling career and role as a series regular in Grace and Frankie, where she received far more acclaim.
