Corrected entry: In the scene where Fergus first sends out his Gyarados(where he's crossing the ocean to New Island on it), it's lips are blue very briefly. I guess the water was pretty cold.
Corrected entry: Early in the film, Ash defeats a Golem using one of Pikachu's electrical attacks. Electrical attacks can never harm a Golem, no matter how much stronger the electrical Pokemon is.
Corrected entry: When one trainer sets off to the castle, he is riding Pidgeot. In a later shot he is now riding a Fearow.
Corrected entry: The male trainer with the Gyrados claims all his Pokemon are water types. When he introduces his team, a Nidoqueen is there. Although Nidoqueen can learn water attacks, its classified as a Poison/Ground type.
Corrected entry: When Ash is fighting the pirate trainer near the beginning of the film, and the pirate guy throws out the rest of his Pokémon, Ash sends his Pikachu, who uses Thunderbolt to knock them all out. The thing is, one of the Pokémon sent out was a Golem - a rock/ground type. Electric attacks have no effect on ground type Pokémon, so, even if Pikachu's Thunderbolt was that powerful (which is ridiculously unrealistic if you've played the video game), the Golem should have still been standing.
Corrected entry: When Mew appears for the first time, someone shouts Mew. It appears to be Prof. Oak's voice, but Oak isn't anywhere NEAR New Island. So, why would we hear him talk?
Corrected entry: In Pikachu's Vacation, after the song has finished, all the Pokemon run towards the park, knocking Pikachu over. The last Pokemon to go past is Psyduck, who steps on Pikachu's head. We then move over to Togepi, with Squirtle, Bulbasaur, and, strangely, Psyduck. I thought he was in the park?
Corrected entry: During the introduction, there are two visual mistakes with the trainer's Venomoth: 1: The three horns on its head are all about the same size; the middle horn is meant to be at least twice the size of the other two. 2: The color of Venomoth's eyes are white; they are meant to be blue.
Corrected entry: In the scene where trainers are flying to new Island, a boy on a Pidgeot takes off. A few frames later, and Officer Jenny appears. We then see him take off again, except this time on a different Pokemon, a Fearow.
Corrected entry: There was actually supposed to be a bit added on to the start of the movie explaining how Mewtwo could talk and everything, but was cut in the actual movie. Apparantly Mewtwo was raised by a geneticist's cloned daughter who taught him everything, but she died. Mewtwo was angry at humans for taking it friend away and then the movie continues in similar fashion to what we're used to.
Corrected entry: During the opening theme song, the "pirate" trainer that challenges Ash at the end of the battle throws five or six Pokeballs. Of those six, four hit the ground and release Pokemon and of those four Pokeballs only three Pokemon show up. Where did all the Pokemon go?
Corrected entry: If Team Rocket have been after Pikachu all this time, why would they say "Who's that pokemon" when Pikachu's silhouette pops up?
