Edge of Tomorrow stars Tom Cruise and Emily Blunt. If that alone isn't enough to send you to the movies / dvd shop / netflics, read on.
Imagine Groundhog Day set in a futuristic world with a total military flavour (which I thought would kill the movie, but it worked). The movie's slogan: "Live. Die. Repeat" is very well chosen, but there's more to the story than action. The plot is smart, the acting superb, and the ending will make you think, and think some more, and repeat.
Don't be put off by the robot-like images on the posters. Just see the movie.
