Michael Jackson
Given Michael Jackson’s knack of putting in seemingly effortless and showstopping performances, filming his 1984 Pepsi commercial should have been a cinch for the star. Tragically, that wasn’t quite the case, though: after a pyrotechnic went off prematurely, its sparks ignited the King of Pop’s hair and gave him some rather shocking burns. What’s more, 3,000 fans witnessed the painful and rather embarrassing moment on set.
