Remember that scene where the Wicked Witch Of The West says something evil and then disappears in a puff of smoke? Well, it almost killed the actress who played her, movie legend Margaret Hamilton. Because the director wanted to see Hamilton for a brief second in the puff of smoke to give the illusion better, the trap door was delayed to open a few seconds after the explosive sparks showed on screen. Unfortunately, the sparks had a bad reaction with the petroleum-based make-up on Hamilton's face, causing 3rd degree burns to her hands and 2nd degree burns to her face, which required 6 weeks of recuperation at home and hospital. Amazingly, Hamilton didn't sue, saying: "I won't sue, because I know how this business works, and I would never work again. I will return to work on one condition no more fireworks!" You've got to admire her ballsyness really, she went on to have a wonderful career and didn't really seem to hold any ill will, thankfully.
