Continuity mistake: During the showdown's sword fight between Lansing and Faisal in the palace hall, there is a far-off shot in which the blade of Lansing's sword can just barely be seen bending off at an unnatural angle, revealing it as a prop.

Revealing mistake: When displaying the information of Ash, Pikachu, Tory, and Torkoal, the information is filler text. (00:22:54)
Factual error: Throughout the film, Lieutenant Choi and his platoon use a radio with a handset to communicate with their base. The radio however has an H-250 handset, which wasn't introduced until 1987, and the film takes place in 1972. The radio handset should be the H-189, which is the correct model for the Vietnam war from 1966 onwards.
Continuity mistake: When Yugi is first seen assembling the Millennium Puzzle, there are some books on his shelf. The fourth, fifth, sixth, and seventh books on the shelf appear to be slanted by a few degrees to the right. In a closer shot of the shelf, the books are slanted much further to the right. (00:00:57)
