In the original script, there was supposed to be an elaborate fight between Indiana Jones and the swordsman in "Raiders of the Last Ark."
However, according to a 2014 Reddit AMA with Harrison Ford, he couldn't do it because he was sick with dysentery. So instead, his character just shoots him with a gun, and the scene is over in a few seconds.
"... It was meant to be the ultimate duel between sword and whip. And I was suffering from dysentery, really, found it inconvenient to be out of my trailer for more than 10 minutes at a time," Ford wrote.
He continued, "So he drew his sword, the poor guy was a wonderful British stuntman who had practiced his sword skills for months in order to do this job, and was quite surprised by the idea that we would dispatch him in five minutes."
