Blunt guested on Conan Wednesday and regaled Conan O'Brien with a story from the Edge of Tomorrow set: The time she almost killed Tom Cruise.
"I hear him going [quietly], 'Brake. Brake. Brake,'" Blunt recalled of a scene that involved a tricky bit of stunt-driving. (The pair did their own stunts on the film.) "'Em, brake the car! Brake the car!'"
"And I left it too late and so drove us into a tree … and I almost killed Tom Cruise," Blunt finished. She says she was initially a little irritated that Cruise was backseat driving during their scene, but eventually swallowed her pride, realizing that there was no way she was more qualified in driving than Tom "Mission: Impossible" Cruise.
Edge of Tomorrow hits theaters June 6.
