The thing is, though, while KT would have had influence on the anime, his work is primarily the manga.
KT's primary work: The manga
The Japanese anime is an adaptation that I presume KT had influence in.
The anime's English dub is an adaptation of that adaptation, with presentation & such that KT was much less involved.
As for Pyramid of Light not being contradictory, it still claims Anubis was destroyed 5000 years ago, that there was a Dagger of Fate involved, that Pegasus made a card to rival the gods yet never released it, etc.
And for what it's worth, Solomon says the PoL looks like a Millenium Item. (Also, reading trivia, apparently the English version of PoL has several edited, omitted or switched scenes. The Japanese dub of the movie is 11 minutes longer.)
The movie also asserts Atem commanded some monsters away that appeared when the Millenium Puzzle was completed, which apparently also happened at the same time as the discovery of the Tomb of Anubis.
The movie also claims Yugi beat Kaiba to win the Battle City finals. Likely an error, as it was Marik who was 2nd place.
Also, what of the timeframe they give "In the 3 short years since he started playing Duel Monsters, Yugi Muto has risen to international stardom, by becoming the worldwide Duel Monsters card-playing champion!"
It shows footage of Yugi vs Strings to the public, but only Kaiba & Mokuba saw that duel. Did KaibaCorp record it & release the footage or something?
There's also the problem of it supposedly taking place right after Battle City... but showing footage from the Egyptian Gods vs Leviathan on those same TV screens.
This scene is from an arc that happened after the movie was set. Before this movie's duel, Yugi never had all 3 Gods behind him all at once.
I'd like to know when a fight from the future got recorded!
