In the climactic battle scene, Japanese soldiers are shown firing the infamously misnamed Japanese "knee mortar" with the buttplate placed against their knee. This would've resulted in a broken leg. Allied soldiers mistakenly believed that this mortar was fired from the knee because of the curvature of the buttplate.
Towards The End Of The Film A Female Gorilla Fighter Was Charging Towards The Japanese When She Was Shot. The Blood Pack Used Began Spilling Out Before The Explosive Charge Fired To Make It Look Like She Was Shot. And The Explosive Charge Fired Off On Her Shoulder Not Her Chest Where The Blood Began To Show.
