John Wick directors Chad Stahelski and David Leitch detail how the film’s financiers pushed back on one detail regarding Keanu Reeves’ character. Directed by Stahelski and Leitch, though the latter was uncredited, the 2014 action film follows the relatively simple story of a legendary assassin who comes out of retirement to seek revenge against the men who killed his puppy, which was a final gift from his late wife. The movie was a surprise success and launched a successful franchise, with Reeves returning as John Wick for three sequels from 2017 to 2023.
