As Battleship launches this week, we present Part 1 of an exclusive, four-part look at the greatest alien invasion blockbuster to be based on a board game! So batten down the hatches for a clip-filled spectacular, with debriefs from captain Liam Neeson, first mates Taylor Kitsch and Alexander Sarsgard, and all-action gunner-unner-unner, Rihanna.

Battleship is in cinemas now.
