What are those?
From the 2012 movie “Battleship”...based sort of on the old Battleship board game.
In the movie, the aliens had all sorts of neat weapons including these spinning, multi-teeth, metal-chewing killer balls. The balls were fired from the alien ship, landed on the opposing ship, burrowing into the ship and destroying everything in it’s path. It was “abandon ship” time at that point.
No worries though...the US Navy eventually kicked alien butt.
Wasn’t a bad movie.
