Battleship teaser trailer now online

The countdown has finished and the official Battleship website is now fully online - including the film's teaser trailer.

The alien threat is shown for the first time and there's plenty of Brooklyn Dekker on show. Meanwhile, Taylor Kitsch gets most screen time, Alexander Skarsgard pops up momentarily and if you're observant enough there are two minuscule glimpses of Rihanna.

The site has also added a plot synopsis, one official image, a desktop wallpaper version of the film's poster, plus a Twitter skin and IM logo.

But best of all there are links to the Hasbro website and to play different online versions of the Battleship boardgame. “You sank my battleship!” etc.
