Due to his condition, Carmel's primary work was in carnival sideshows, including appearances at Hubert's Dime Museum and Flea Circus on West 42nd Street in Times Square, Milt Levine's World of Mirth show, and in the 1960s in Ringling Bros. and Barnum & Bailey Circus (which billed him as being 9 feet and 5/8 of an inch tall, and 500 pounds). He also acted in a few films, such as the science fiction horror film "The Brain That Wouldn't Die" (1962) and "50,000 B.C. (Before Clothing)" (1963).
