Emily Blunt "almost killed" Tom Cruise.
The 31-year-old actress got behind the wheel for a scene in their new movie Edge of Tomorrow but things went wrong on the second take - when she was advised by stunt experts to go "a bit faster" - when she ignored her co-star's advice.
She recalled: "I tear down this part and Tom's being very quiet behind me.
"I hear him under his breath as I approach the right-hand turn, going 'Brake, brake, brake. Brake. Brake, brake, brake... Oh God. Brake, brake, brake. Brake it hard! Brake hard!'
"I left it too late, and so drove us into a tree...I almost killed Tom Cruise."
The British actress admits she was foolish to ignore the "annoying" advice but was happy she and her 51-year-old co-star were able to laugh off the incident later.
Speaking on Conan, she said: "When I first heard 'brake,' I thought, 'Ah, shut up.' As if I knew more about stunt driving than Tom Cruise! I mean obviously he knows nothing. I've got this.
"[Afterwards] I was just laughing and he was laughing and I told him, ' I thought you were being so annoying' and I apologised."
