Martin Kove

Injured his hand during the fateful fight scene between his character, John Kreese, and Mr. Miyagi in "Karate Kid Part III Karaté kid - Le moment de vérité II (1986). The effects team ill-timed one of the car-window-shattering shots, causing Kove to inadvertently break the prop window with his own fist. He sustained several injuries to his hand but continued filming.

[on one of his most famous roles, in Le moment de vérité (1984)] Over the years, kids have come up to me in places like supermarkets, and hit me and said things like, "You hurt Ralph (Ralph Macchio)!". It makes me feel like the Darth Vader of the contemporary cinematic world. As Sensei John Kreese, I'm truly hated and I love it. I had no idea how much anxiety people would be releasing by hating this character.
