Many dwarves were also cast as a series of characters named Munchkins. In a ghoulish behind the scenes tale, at one point where most of the characters in Dorothy's troupe (minus the Cowardly Lion) are following the Yellow Brick Road that is to lead to the Wizard, movement in the background before the scene ends is reportedly one of the dwarves hanging himself from a tree on the set.
It was reportedly believed a male munchkin had fallen in love with a female munchkin on the set, but was driven to despair when she did not love him back, thus causing him to hang himself.
Status: False. No actor name, nor death certificate has ever been released of this alleged incident. With the movie industry being pretty new at the time, this could have warranted enough controversy (if this event actually happened) to cause the film’s release to be delayed, if not banned altogether, as only seven years before, a movie called Freaks was banned, which, several decades later, is still banned to this day in some countries (even though no set death occurred, the movie was banned because real human freaks were used in the film).
Real life birds were allowed to wander the sets in order to add a touch of realism, as this movement during the scene in question was just a big bird in the background stretching its wings.
