Other mistake: Franz gives up 1000 life points to destroy all monsters on Jaden's field, going from 2200 to 1200. Later, Franz activates Winged Dragon of Ra's secret ability, allowing him to sacrifice all but 1 life point to add it to Ra. However, when this happens, his life point count starts at 4000, when it was 1200 earlier. Ra gains 1199 attack points, so it does gain the correct number of points, but it was still wrong for the life point count to read 4000. (00:12:45 - 00:14:30)
Continuity mistake: When Chumley shows Jaden the Skyscraper 2: Hero City card, in the shot of Chumley raising the card, he is standing at an angle 90° perpendicular to Jaden. When the shot cuts, he is facing Jaden directly. His hand also goes from raised to lowered between shots. (00:03:45)
