Sean Kanan "nearly died" on the set of 'Karate Kid III'. The 55-year-old actor - who starred as antagonist Mike Barnes in 'The Karate Kid Part III' and 'Cobra Kai' - suffered internal bleeding when filming a fight scene in the third instalment of the franchise and recalled the incident as the "scariest moment" of his life. He said: "I passed out in the Dunes Casino and it turned out that the pain in my leg was internal bleeding and it was the blood dripping down on my femoral artery.
