Rupert Friend shot himself in the head while filming Hitman: Agent 47 - and the accident made it into the movie.
The 33-year-old actor accidentally fired a blank which bounced up off the floor and struck him on the face while working on the action movie, and he was "amazed" not to need stitches on the wound.
He told the New York Post newspaper's Page Six column: "I shot myself in the head.
"You fire blanks, but the guns eject real brass, hot cartridges. They're like 400 degrees ... The cartridge ejected, hit the ground, bounced up and cut my head open.
"It was fine in the end, which I'm amazed about, because I've had head wounds before and they bleed like all hell."
