It's no secret that Tom Cruise loves to do his own stunts in all of his action movies, but his Edge of Tomorrow costar Emily Blunt may have actually given him a scare when they were filming their latest project together. Emily revealed on Conan on Wednesday night that she caused a car accident on the set of their movie while she was shooting a complicated car chase scene where she was driving and Tom was in the passenger seat. Emily accidentally went too fast during one of the takes, resulting in their car running into a tree. "I almost killed Tom Cruise," Emily said. Luckily, it sounds like Tom wasn't too shaken by the incident. Watch Emily tell her hilarious story above.
