Pokémon 3: The Movie (lost first draft of anime sequel film script; late 1990s)
The Pokémon 3: The Movie, released in Japan in 2000 as Pocket Monsters the Movie: Lord of the "UNKNOWN" Tower, originally had a completely different plot to the version released.
It had a first draft written by the late Takeshi Shudo, the main writer of the anime series up to that point as well as the first two movies. He posted the information mentioned below on his blog.
The original plot would have delved into the mystery of how the world came to be inhabited by Pokémon and what happened to the real world animals that once existed in the past. This would have been explored through the discovery of a fossil in the Pokémon world; the fossil of a real-world Tyrannosaurus rex. The fossil would be restored back to life, leading to the creature going on a rampage across the Kanto region. The anime's main protagonists, Ash, his Pikachu, Brock and Misty, and even the show's main antagonists, Team Rocket, would have spent the movie bringing the dinosaur's rampage to an end.
Shudo spent half a year devising this particular plot, which was shot down by the producers under the reason that:
"A story where a bunch of minerals gain consciousness and comes to life won't be a hit".
