Continuity mistake: When Gipsy Danger is lifted by the Kaiju in Hong Kong, they end up well above the clouds, and when Gipsy falls she eventually breaks through them. But in the shots when she is falling, you can see that there are no clouds around Hong Kong for miles. That, and Pentecost has a clear view of Gipsy through his binoculars.
Continuity mistake: When the three Jaeger team are taking on Otachi and Leatherback, Striker is behind Cherno and Typhoon during the fight. However, Striker is in front of them on the radar as Stacker tells Striker to not engage. Cherno and Typhoon were in the same positions on the radar and in the real fight.
