Easter Eggs
Raccacoonie

2001: A Space Odyssey Homage

Wong Kar-wai Style Universe
The universe where Evelyn is a movie star and Waymond is a CEO is shot in the visual style of Wong Kar-wai (specifically In the Mood for Love), utilizing step-printing, a green hue, and 4:3 aspect ratio.
Super Smash Bros. Reference
