Like the title says, I was hoping to see if anyone picked out some of the references or homages in John Wick 3. Some of the ones I noticed while watching:
Game of Death - Using a current NBA star to fight the hero, really emphasizing the size disparity between the two. Much like Kareem and Bruce Lee's famous fight in Game of Death, Keanu takes on 76ers Boban Marjanovic in the New York Public Library.
The Good, The Bad and The Ugly - Seconds before his excommunication takes effect, John is hiding in a weapons antiques store and builds himself a revolver. This is clearly a homage to the scene in Sergio Leone's classic where Mexican outlaw, Tuco does the same thing. Even down to listening to the chambers click.
The Villainess - In one of the coolest action movies of 2017, female assassin Sook-Hee gets chased through a tunnel by motorcycle riding ninjas with samurai swords. If you haven't seen The Villainess and enjoy films like Wick and The Raid, you need to check this movie out ASAP. Clearly John Wick director Chad Stahelski has seen the film and gives his homage to the scene as John rides through NYC in a very similar sequence.
Those were some of the obvious ones that I noticed while watching John Wick 3. Was hoping you guys might be able to add to this list and if anyone was able to pick out any other references to other action films.
