Rihanna and foxy bikini model Brooklyn Decker provide some interesting diversion in the latest trailer for “Battleship,” but the CGI sequences seem to be the real stars of this movie.

The new clip, the third released by Universal Pictures, went viral today (Feb. 13) and provide some closeups of the alien nemesis facing U.S. Navy ships.

Although the Barbadian singer and the bikini model have relatively modest roles in the movie, they can’t seem to stop popping up in the trailer.

The film produced by toymaker Hasbro, which makes the popular Battleship game, is following the same formula that made the “Transformers” movies popular. (Yes, it also makes transformers toys.)

There’s lots of action and lots of big special effects, with a sprinkling of sex and romance to maybe make it a date-night movie.

Peter Berg is directing and the film also includes a solid cast with Taylor Kitsch, Alexander Skarsgård and Liam Neeson.

Unlike most other sci-fi movies, the aliens’ point of view will be included in the film. They initially land on earth to develop a power supply deep in the ocean. But a fleet of warships out of Pearl Harbor stumbles on them and all hell breaks loose.

The idea is to give viewers the same perspective on the enemy as they would have in a game of Battleship.

For the record, Rihanna plays Petty Officer (GM2) Cora Raikes, who serves as a weapons specialist on the USS John Paul Jones. Decker plays Sam Shane, a physical therapist and love interest of Lt. Alex Hopper, a Naval officer played by Kitsch.

The film, which cost a reported $200 million to make, opens May 18 in the United States and Canada. Check out the trailer below.
