Plot hole: The Kaiju's EMP pulse fries all electrical circuits next to him, and affects the base as well. If that's true, how did the helicopters carrying Gypsy survive the blast without having their electronics fried? EMP pulses induce current in all electronics regardless of whether they're powered on or not.
Factual error: Gipsy Danger's fist bumps into an office table as it screeches to a halt. The Newton's cradle on the table has an impossible reaction. All of the balls would simply sway in parallel, and not the 'classic' reaction displayed in the movie.
Other mistake: In the scene from Mako's memory, the terrified little girl stops crying and smiles when Pentecost emerges from the Jaeger's head/cockpit. But if the Jaegers are 250 feet tall, how could she possibly have seen him? It's not kneeling when she looks up at him.
Trivia: Although they play father and son, Max Martini is only fourteen years older than Robert Kazinsky.
Stacker Pentecost: Today at the edge of our hope, at the end of our time. We have chosen to believe in each other. Today we face the monsters that are at our door, today we are cancelling the apocalypse!
