One of the hardest beings from Classical Mythology (well, three beings, actually) to properly depict is (are?) the Gorgons. Three sisters, who were cursed with having living snakes for hair and being generally so ugly that to see them in full view would literally petrify you with fear. For obvious reasons, it’s going to be darned difficult to make any image of them that’s even close to the Real Thing.
Most artists have gone with making the woman “plain”, and using basic snake forms about six inches long to frame her face. Easier to do in animation than in live action.
Hammer Films, in this interpretation of the legend, decided to go with a headdress of balloon-like snakes that could be made to move through the use of air hoses. It barely worked. They did, however, make up for it – mostly – by limiting the Gorgon’s on-screen appearance.
