After "Freaks", Eck was featured as a bird creature or "Gooney Bird" in three Tarzan movies: "Tarzan the Ape Man" (1932), "Tarzan Escapes" (1936) and "Tarzan's Secret Treasure" (1941). In order to create the bird costume used by Eck for the Tarzan films, footage which was filmed during the production of "Freaks" in 1931, a full body cast was taken of him. When the Eckhardt home was facing foreclosure due to the oncoming Great Depression, Eck performed for the Ripley's Believe It or Not! Odditorium at the 1933 Chicago World's Fair. It was there that Eck was billed as "the Most Remarkable Man Alive".
