FILM 1351: JOHN WICK
TRIVIA: According to Keanu Reeves, he did 90% of his own stunts in the film.
Keanu Reeves learned and memorized the nightclub fight sequence the day that the scene was filmed.
The Red Circle Bar is a clear allusion to one of the main influences for this film: Le Cercle Rouge (1970).
During hand to hand combat scenes, John Wick shows himself to be a Judoka and use japanese traditional jujutsu. Judo is a Japanese martial art emphasizing throws. Specifically, Wick repeatedly uses head throws and arm throws. On the other hand, his rival assassin, Ms. Perkins, uses Brazilian Jiu-jitsu (employing a Kimura shoulder lock, the crucifix position and using her leather jacket as a Gi to perform a wing choke in her fight against Wick in the hotel room).
The Red Shirt Henchmen are an homage to Star Trek (1966).
