That Kevin Costner comeback that kicked off last summer with the rumor that the actor would co-star in Django Unchained (though that proved fruitless), which then carried over to his casting in Man of Steel, an Emmy-winning role in Hatfields & McCoys, and a major part in Jack Ryan just continues to reap huge benefits for the star. As had been rumored back in August, Costner has now officially signed on to star in director McG‘s next film, “a gripping action tale” that’s been penned by Luc Besson and Adi Hasak. Currently untitled, the film has previously been referred to as Three Days to Kill, though perhaps everyone decided that moniker was just a touch too spoilery and has decided to lay off on letting everyone know how long Costner will have to, you know, kill someone. A press release from Relativity Media describes the film as such: “the thriller explores a story about Secret Service Agent Ethan Runner who discovers he’s dying and decides to retire in order to reconnect with his estranged family. But when the Secret Service offers him access to an experimental drug that could save his life in exchange for one last assignment, he soon finds himself trying to juggle his family, his mission, and the drug’s hallucinatory side-effects.” Wait, there are drugs involved in this? Is this The Bourne Legacy fan fiction? You can read the full release after the break, if you’re just that into Kevin Costner news.
