As I was watching Stanley Kubrick’s 2001: A Space Odyssey (1968) the other night, I realized that the interior of the space station that Floyd arrives on after traveling in the Pan Am space plane looked familiar. 

And rightly so - it appears very similar in color and design to the world in Eureka’s and Renton’s minds when they speak to one another from separate areas in the cave of episode 16! Not surprising that this would be a reference, seeing as Space Odyssey is one of the most culturally-influential sci-fi films created.

And its interesting that the E7 staff chose the design of the space station hub as well - almost like a hub of communications between Eureka, Renton and Anemone (who all appear in this sequence).
