An aging spy who wants to start a new life is forced to do one last job to literally save himself from death in the first trailer for Three Days to Kill. Kevin Costner stars as Ethan Runner, a retired covert agent who becomes mysteriously ill while watching over his teenage daughter (Hailee Steinfeld). Amber Heard plays Runner's former colleague, who offers him a cure if he can kill an international terrorist in just three days' time. Take a look at the first footage from this action-thriller, and check out the poster as well.
