Continuity mistake: When Yugi and Kaiba's monsters have been destroyed, the two of them turn around to face the demons. They are side by side when this happens, but when the shot cuts, Yugi is suddenly in front of Kaiba. (00:14:06)
Continuity mistake: A creature jumps in between Yugi and Kaiba and then goes through a wall. A giant hole is left in the wall that is circular shaped, but when the shot cuts to an angle inside the wall, the hole is more of an oval shape. (00:11:53)
Continuity mistake: When the main characters meet up with Hawkins, Rebecca, and Devlin, in the shot of Yugi saying "Professor, I'm glad you're all right," Joey is standing directly behind Yugi. In the next shot, Joey is standing on Yugi's left. (00:09:49)
