Earth has been invaded by space aliens, and Europe is already lost. Though no combat veteran, Major Bill Cage (Tom Cruise) is thrust into a kind of second D-Day landing on the beaches of France, where he is promptly killed in battle. Yes, 15 minutes into the movie Tom Cruise is dead—but this presents no special problem for Edge of Tomorrow. In fact it’s crucial to the plot. The sci-fi hook of this movie, adapted from a novel by Hiroshi Sakurazaka, is that during his demise Cage absorbed alien blood that makes him time-jump back to the day before the invasion. He keeps getting killed, but each time he wakes up he learns a little more about how to fight the aliens and how to keep a heroic fellow combatant (Emily Blunt) alive.
It might sound laborious, and the inevitable comparisons to Groundhog Day are not far off the mark. But the movie is actually ingenious in doling out its herky-jerky storytelling.
