Buddy Ebsen
Buddy Ebsen was originally cast as the Scarecrow in the 1939 film “The Wizard of Oz” before he switched parts with Ray Bolger to portray the Tinman. Unfortunately, the metallic paint used in his makeup for the character contained toxic aluminum dust. Ebsen had to quit the film after his nearly-fatal allergic reaction and afterwards he suffered with lung issues for the rest of his life.
