Andre the Giant needed an ATV to get him to shooting locations, and he was always trying to get Cary Elwes to drive it. Elwes eventually relented, but on his first time driving it, he hit a patch of rocks as he was shifting gears, which caused his foot to slip from the clutch and eventually become wedged between the pedal and a rock. His left big toe was bent straight down and was broken, which he tried to conceal from director Rob Reiner. Eventually he had to confess, and they worked shooting around his swollen toe and limp. You can notice it in the scene right before Buttercup pushes him down the hill; he sits down with his leg extended, because he wasn't able to put weight on the foot. In the next scene when he and Buttercup head into the Fire Swamp, he has a strange hop in his step.
