Audio problem: Parzival starts to walk away from the Office Party recording as Halliday says "Why can't we go backwards for once." Parzival stops and turns around, telling the Curator to stop and go back right as Halliday finishes saying "Really put the pedal to the metal you know?" The Curator then replays that same recording over again. However the timing is off - it is actually two different recordings of the actor saying these lines and not the same message replayed. He says it a full second faster the in the replay. (00:24:55 - 00:25:25)
Continuity mistake: After using the Cataclyst to wipe out everyone, Sorrento exits his gaming rig, falling to his knees and removes the groin section, handing it to the guy as they walk through the door. Next shot we see Sorrento with the piece back in place. In fact, he runs his hands over it as he walks past.
Continuity mistake: Before the race starts, Aech is towards the front of the line up. Parzival had to head to the back so he could get coins for fuel. Art3mis pulls up right beside Parzival on her bike in the line up towards the back. As the race starts, there is a shot of Art3mis blasting through the lines on her bike and cutting way ahead of a lot of the cars and leaving Parzival in the dust as she takes off. But only a few seconds later as they reach a part of the road where there are trains coming, Art3mis is suddenly back behind Partzival again. (00:12:50 - 00:13:20)
Trivia: When Wade is talking about how when you die in the game, you lose everything you ever worked for, there is one shot of a little girl throwing her OASIS goggles off and screaming in a fit of rage. Behind her on the wall is a poster for the 1982 game, Donkey Kong Junior. Also behind her you can see a blue Care Bear plush toy on her bed, as well as some small Care Bear figurines on the shelf against the wall to the right. (00:06:10)
Continuity mistake: In the first race, there is a delay between the green light and the green fireworks that start the race. However after Parzival figures out the clue in Halliday's Journal and comes back to the race again, when the lights and fog horn start it happens differently. The fireworks and the green light with the long honk happen at the same time and the cars take off. (00:12:35 - 00:26:00)
