Character mistake: After Wade is going over the second clue in his mind and trying to figure out what part of Halliday's past is he trying to escape from, he looks over the wall of article clippings and notes he has hung up. When the camera stops on Karen Underwood's obituary, there is a hand written note beside it listing movies set in New York, with the sentence "Set in New York" underlined. This apparently him looking for clues in films set there for the race challenge that is in Manhattan. However, one of the films he has written on that list is Mad Max, which takes place in Australia, not New York. (00:35:00)Quantom X
Character mistake: When Wade is trying to figure out the second clue in his van, he scans his bulletin board that has Karen Underwood Morrow's Obituary. The dates show 1975 - 2034 which would make her 59 (or 58) at the time of her death, but the article to the left of the obituary states that she was fifty six years old at the time of her death.
Continuity mistake: Right in the beginning, Wade hops out a window from his home and starts walking beside it to the edge to climb to the next level down. As he starts walking he passes by another window with a curtain. It then cuts to a closer angle and suddenly the window no longer has a curtain. Also a wire appears on the wall in front of him. And you can tell it is the same house, not a time jump, as the rust at the top of the window frame is exactly the same. (00:01:15)Quantom X
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
