"We came up with the idea of my character being kind of an anti-hero, not a soldier," Cruise told MTV News on the red carpet for the film. "A coward, and not ashamed of it either."
So if Cruise spends a lot of the movie as a coward, who does the ass-kicking? Clearly, it's the one and only Emily Blunt.
"Emily is the one who is a soldier," Cruise explained, "so you have this very unique relationship."
And Blunt didn't just get kill a lot of invading aliens in the sci-fi actioner. She got to kill Cruise, over and over and over again.
"In many violent ways, mercilessly," Blunt said. "It was really exciting. I would laugh after each take, just at Tom's face, going 'Oh c'mon.' "
With so many times killing arguably the biggest movie star on the planet, Blunt had to have a favorite.
"I sort of liked the casual one where I just don't look and I just kind of shoot him like that," Blunt said. "It's sort of like, oh God, it's so boring. I can't be bothered."
Get your fill of Blunt killing Cruise and both killing aliens in "Edge of Tomorrow," in theaters now.
