Factual error: The third key Easter egg was actually a color-changing flashing pixel in the Atari Adventure game. You had to grab the purple bridge (they looked like outward facing brackets) and go into a box in the lower left corner of the blue maze and move along the bottom left corner. In the movie, it was picked up in the invisible maze. The wall you walk through then flashes along with the pixel, and you may move through it as shown in the movie to see the author's name.
Continuity mistake: At the end of the race, Parzival is accelerating towards the finish line as fast as he can but King Kong smashes down into the road in front of him. In the first person perspective of Parzival through the windshield of his car, he comes up almost right at King Kong with only 2-3 car lengths maximum between him and Kong. It then cuts to a view of Parzival's face as he reacts, and has time to react before switching camera angles again and now the car much much further away from Kong allowing him time to slam the brakes and skid to a stop from moving at high speeds.

Trivia: In the video that Halliday left behind after his death, you see floral arrangements around his coffin that are in the shape of the Star Trek's Federation symbol and one of the Enterprise. But the really cool thing is his coffin is actually a photon torpedo, exactly like Spock was put in after his death at the end of Star Trek II: The Wrath of Khan. Complete with the blue Federation flag draped over the end of it. (00:08:05)Quantom X
Trivia: The car that Parzival uses in the race is the DeLorean, complete with all it's customization and advances, from the Back to the Future movies. Steven Spielberg, the director of Ready Player One, was also the Executive Producer of the Back to the Future trilogy with his company Amblin Entertainment. Spielberg only allowed the DeLorean to appear as a reference and tribute to BTTF director Robert Zemeckis, rather than himself. Despite Spielberg's overwhelming impact on pop culture throughout the decades, direct Spielberg references were rather deliberately omitted from "Ready Player One" by Spielberg himself. Ironically, he intended to include references to "Close Encounters of the Third Kind" (Spielberg's second blockbuster after "Jaws"), but he couldn't negotiate a licensing agreement with Columbia Pictures and Warner Bros.

Wade Watts: A creator who hates his own creation. A hidden key: a leap not taken. Retrace your steps, escape your past. And the key of Jade will be yours at last.
Halliday: I created the oasis because I never felt at home in the real world. I just didn't know how to connect with people there. I was afraid for all my life, right up until the day I knew my life was ending. And that was when I realised that... as terrifying and painful as reality can be, it's also... the only place that... you can get a decent meal. Because, reality... is real.
