VIDEO : Arnold Schwarzenegger's Mr. Freeze Costume Almost Killed Him

Batman and Robin was a powerhouse cast wise, including the likes of Arnold Schwarzenegger playing the fan favorite villain Mr. Freeze. Unfortunately, the process to make him appear like Freeze was far from flawless, and in some ways deadly. Make-up artist Jeff Dawn recalled the elaborate process of getting Schwarzenegger into costume. Aside from the layers of makeup, it also required a complicated LED system in Arnold's mouth for closeups, including a rather dangerous placement of the LED's battery. "When you put it in Arnold's mouth, Arnold's saliva would creep into the seams of this thing and attack the batteries. The batteries would immediately start disintegrating and start putting out battery acid into Arnold's mouth," says Dawn.
