what really fascinated me is Prince Randian aka human caterpillar.
Freaks, a 1932 movie starring real life human marvels, is available for download at Archive.org. It stars the handsome and talented, 18-inch tall Johnny Eck (shown here in black jacket and bow-tie). I first saw Freaks when I was about 15, and when Eck came running across the screen using his hands and arms, I was dumbfounded.
