Gerard Butler is reported to be in talks to star in Hunter Killer.

The P.S I Love You actor has been approached to appear in the film, which is based on the novel Firing Point written by George Wallace and Don Keith.

The movie follows a rogue Russian general who kidnaps his country's president, who is pursued by an untested submarine captain – the role Butler is said to be up for.

Antoine Fuqua has signed up to direct the movie, which is scheduled to begin shooting either later this year, or early 2012.

The release date of 21 December next year has already been set in the US.
