"In one scene in Princess Bride, Cary Elwes’ character Westley gets clonked on the head pretty hard by the six-fingered man, played by Christopher Guest.
But when it came time to film the scene, the stunt didn’t look realistic enough. So Elwes suggested that Guest knock him as hard as he could using a real metal sword.
"Because of the angle, we couldn't sell a fake blow well enough for the camera, so I told him to just hit me hard," Elwes wrote in his book, As You Wish.
"And that’s the last thing I remember. I woke up in the hospital.""

"Camp may be the place for bonding, but this boot camp was really tough, and the fact that Matt was at home relaxing definitely created a divide. It was so horrible that after day four, everyone wanted to quit, but Tom Hanks encouraged them to stick it out. Matt said that when he eventually showed up on set there some resentment from the guys, and it translated onto the screen."

"Michael J. Fox In ‘Back To The Future Part III’"
"In one scene, Marty gets strung up on the famous Hill Valley clock tower. In what was without a doubt something he later regretted, Fox said “Sure” to performing the stunt himself.
The plan was for him to use his hand to keep the noose from tightening around his neck and actually strangling him. In practice, he couldn’t get his hand into position and actually blacked out for a minute, until the crew realized what was happening and saved his life."

"Jason Segel Didn’t Know His Character’s Father Was Going To Die On “How I Met Your Mother”"
"The meticulousness with which the film was created had a cost: Shelley Duvall’s wellbeing.
