Just in case the "kids love board games!" philosophy behind making a Battleship movie doesn't pay off, Universal has added a Plan B: the kids like that Rihanna, right? According to Variety, the pop star has signed on for Peter Berg's adaptation of the peg-and-boat board game, joining Taylor Kitsch, Alexander Skarsgard, and, of course, aliens in the inexplicable film. The story doesn't mention who Rihanna wil play, but it does note the film "takes place across the seas, over the skies and land in a battle for planet survival against a superior force." Classic Battleship.
