The appearance of Australian actor Mel Gibson has changed quite dramatically over the years. He seems to reinvent himself with each passing decade. Because of that, you can sometimes forget that he had wild, unkempt hair.
Fortunately, pictures like this exist to remind us all of how he looked. You probably won't be surprised to hear that it was taken during the 1980s while he was making one of the 'Lethal Weapon' films. This look was cool back then!
