Mel Gibson – 5 feet 8 inches tall

Mel Gibson may have such a volatile personality because he's relatively short in stature. Or maybe playing iconic roles like William Wallace and Mad Max have just damaged his brain.

It's surprising when an action star turns out to be anything less than 6 or 7 feet tall, especially one who's part of the 'Lethal Weapon' franchise next to 6'3" Danny Glover.

They can take his life, but they will never take his high-heeled elevators!
