FILM 1525: EDGE OF TOMORROW
TRIVIA: Based on the manga and novel "All You Need Is Kill" by Hiroshi Sakurazaka.
It was never stated in the movie, but in the manga, the reason why Rita uses a melee weapon is because during her "resets" she would often run out of ammo, which resulted in her deaths. Keiji (in the manga) also learned about the convenience of a melee weapon and started using one.
While filming the car chase scene which includes a minivan, Emily Blunt was instructed to drive fast and then to take a right hand turn so that the van would shake. However, Blunt missed her mark and she drove the car right into a tree. She later said that it was both hilarious and terrifying, as she almost killed Tom Cruise, who was in the passenger seat, but both of them started laughing after the incident.
Emily Blunt admitted that after putting on the metal suit, she started crying because it was so heavy (it weighed 85 pounds) and that she would be required to perform action scenes in it for five months. She was jokingly told by Tom Cruise to "stop being such a wuss."
When Emily Blunt's character is introduced, she is doing a "planche" hold. Although she needed a wire for help on long takes, she is actually capable of doing that maneuver without assistance. In fact, when discussing the introduction, a cast member said, "Em, show that yoga move," and she casually demonstrated it.
The default language setup for Cage's battle armor is Japanese, a nod to the novel's country of origin.
Operation Downfall, the name the movie gave the planned invasion, was in fact a real planned invasion: the final invasion of the Japanese Home Islands to end World War II. The real Operation Downfall never happened, as the dropping of the atomic bombs on Hiroshima and Nagasaki brought about the surrender of Japan.
Rita, for her bravery, was nicknamed by the public "The Angel of Verdun." In real life, Verdun was the site in France of the bloodiest battle of WWI in 1916. It lasted almost a year and an estimated one million men on both sides died, and Mons was the site in Belgium of a battle in 1914 and spawned tales of what many consider an otherworldly miracle. A 1914 newspaper short story about the battle, "The Bowmen," written by horror-story specialist Arthur Machen, told the tale of how during the battle, soldiers on both sides saw "supernatural" medieval archers appearing in the sky and causing the enemy to retreat. Despite Machen's attempts to prevent it, his story, which was entirely fictional, quickly inspired a popular and strongly believed account of "the Angels of Mons." The Battle of Verdun occurred two years later and there was no association with angelic apparitions, but Rita's nickname does seem to be inspired by the "Angels of Mons" story.
The sound design of the jacket is the same gun used in Aliens (1986).
At the beginning of the movie, there is a montage of different newscasters, news footage, and public officials trying to deal with the alien invasion. One of the public officials they showed was Hillary Clinton, implying that she was President of the United States. The movie was released in 2014, two years before the 2016 presidential elections.
While preparing for her role here, Emily Blunt was tutored in the Israeli self-defense system of "Krav Maga".
Doug Liman wanted to do the film because it showed a role that Tom Cruise hadn't done yet; someone very bad at what they do.
