Edge of tomorrow 
Edge of tomorrow is science fiction action movie that came  out in 2014.The film takes place in a future where Earth is invaded by an alien race. Major William Cage (Cruise), an officer with no combat experience, is forced by his superiors to join a landing operation against the aliens. Though Cage is killed in combat, he finds himself in a time loop that sends him back to the day preceding the battle every time he dies. Cage teams up with Special Forces warrior Rita Vrataski to improve his fighting skills through the repeated days, seeking a way to defeat the extraterrestrial invaders.The invasion is a disaster for the humans. Cage, despite his inexperience and incompetence, kills a large Mimic but dies covered with its acid-like blood. He wakes up at the airport the previous morning; no one believes his story that he knows the invasion will fail. Cage repeats the loop of dying on the beach and waking at the airport until he  meets Sergeant Rita Vrataski during the invasion, and tells him to locate her the next time he "wakes up".
the next day when Cage dies again, he meets Sg.Rita and he tries to tell her that he came from the future but she doesn't believe at first but then she does because that happened to her too and every time Cage dies she trains him and he becomes better and better in fighting the Aliens ( Mimics ).

The movies ends with Sg.Rita dying and Cage killing the Aliens.
