Oliviers tail isnt real, is it?
No, its a prosthetic (but people have been born with actual tails see the links in the Wet Lab & Library if you dont believe us). Actor David Richmond-Peck not only had to wear a monstrous mechanical necklace that housed all the gears and wires that animated the tail, but he literally could not sit down for several hours while he was wearing the mighty memorable appendage. David had to stand or lie on his stomach, but he was a great sport about it. Wherever he went on set, he always had the biggest tail in the room.
