First official Battleship poster launched

The first official poster for upcoming war flick Battleship has been revealed.

Those unfamiliar with the board game from toy manufacturer Hasbro can be forgiven for thinking it looks like a promo for Titanic 2 .

Perhaps more intriguing is the countdown clock which has begun on the film's official website at - by our calculations it runs out at 9am on Wednesday morning in the UK.

Will it eventually reveal a trailer? Further images besides the poster? The ability to challenge your friends at an actual online game of Battleships? Only time will tell...

Battleship is due in UK cinemas on 18 May 2012.
