Director Chad Stahelski first imagined Yen’s character as similar to Zatoichi, a blind, unassuming older swordsman from a series of 1960s and ‘70s films. However, Yen convinced Stahelski to change the idea, saying, “I get what you’re going for. I just don’t want to be the old, blind guy with a cane. [...] I’d rather be the cool guy in the suit ... It’s ‘John Wick.’ It’s a suit movie. It’s cool!”
