Trivia: Ryu, from Street Fighter, is seen in the first race as an avatar walking among the cars. He is walking away from the camera the way he does in his iconic end game cinematics after victory. (00:10:30)
Trivia: Just before asking the computer to locate his friend Aech, Wade as Parzival is walking along a bridge. Beside him you can see Hello Kitty with two of her friends, Badtemaru and Keroppi walking along with him. Hello Kitty can also be seen again once Parzival enters the Halliday Journals building the first time in the film sitting at a desk studying with someone else. In addition, there is also a Hello Kitty sticker on Art3mis' bike. (00:05:00 - 00:22:50)
Trivia: After Wade puts on the face sensor around his neck, he sets down his glasses on a lunch box. This is a He Man Masters of the Universe Lunch Box, complete with its cup next to it. (00:02:55)
Continuity mistake: Surrento is meeting with I-R0k to get the orb and I-R0k holds up the Steam Punk Pirate King's head. In the close up as he holds the head up, its somewhat above him and close. When the angle changes in the next shot, suddenly he's holding it almost level with his own head and further out. (00:31:55)
Trivia: After buying the Holy Hand Grenade in the shop, Parzival excitedly runs around that display of other items. One such item is the Chucky doll from Child's Play complete with the large kitchen knife iconic to him. This item is also used in the final battle and seen taking out several Sixers just by itself. (00:30:05)
Trivia: While Parzival is showing off Aech's shrunken ships to Art3mis, there are some full ships in the background. One of which is Lone Star's RV from Spaceballs seen while Parzival is showing off the ships in the lunchbox. The clearest view of it is when Art3mis fixes Parzival's hair by the Iron Giant's legs. (00:17:20 - 00:20:00)
Trivia: As Parzival is approaching Aech at the race and asks how she got there before him, there is a blue ninja walking behind Aech's monster truck. This is Sub Zero from Mortal Kombat in his latest design from Mortal Kombat X. (00:11:25)
Trivia: On Planet DOOM, Aech kills a guy with an emoji as a head. This guy drops a weapon that Aech then picks up and it's displayed as the EM1-Rail Gun. The EM-1 Rail Gun is the weapon used by U.S. Marshal John Kruger (played by Arnold Schwarzenegger) in the movie Eraser. (00:05:45)
Suggested correction: From a military point of view it makes perfect sense. AOE weapons would be most likely to hit members of the same squads, companies or battalions. It would make sense for squad mates in the oasis to stick together in stations as well. I just watched that scene. As long as the Sixers are trained soldiers or players it makes perfect sense.
