Harry Earles, Jackie Gerlich, and Jerry Maren in The Wizard of Oz (1939)
In a scene in The Wizard of Oz (1939) when Dorothy, the Scarecrow, and the Tin Man head down the yellow brick road, on their way to Emerald City, a dark figure can be seen deep in the background, with many claiming it to be a hanged munchkin.
The story says that he was upset because the female munchkin that he loved didn’t feel the same way for him. He then decided to kill himself right on set.
