Check out this great new featurette from the film “Battleship” that focuses on the special effects for the film and also talks about how and why the aliens comes to earth.

Here’s the official synopsis:
Peter Berg (Hancock) produces and directs Battleship, an epic-scaled action-adventure that unfolds across the seas, in the skies and over land as our planet fights for survival against a superior force. Inspired by Hasbro’s classic naval combat game, Battleship stars Taylor Kitsch as Lt. Alex Hopper, a Naval officer assigned to the USS John Paul Jones; Brooklyn Decker as Sam Shane, a physical therapist and Hopper’s fiancee; Alexander Skarsgard as Hopper’s older brother, Stone, Commanding Officer of the USS Sampson; Rihanna as Petty Officer Raikes, Hopper’s crewmate and a weapons specialist on the USS John Paul Jones; and international superstar Liam Neeson as Hopper and Stone’s superior (and Sam’s father), Admiral Shane.
