Spoiler alert! We're discussing major details about the plot of Michael Jackson biopic "Michael."

Yes, the new Michael Jackson movie plays the hits from “ABC” to “Human Nature.”

But “Michael” (in theaters April 24) also revisits one of the most traumatizing chapters of the King of Pop’s life.

On Jan. 27, 1984, the then-25-year-old superstar filmed a Pepsi commercial at Los Angeles’ Shrine Auditorium for an audience of 3,000. The shoot went smoothly until the sixth take, as he descended a staircase singing “Billie Jean.” A pyrotechnic exploded behind him, showering the singer with sparks and lighting his hair on fire.

As depicted in the film, he carried on with his performance for a few seconds before the back of his head was engulfed in flames.
