A clearly angered Will Smith stormed the stage and gave Chris Rock a slap after the comedian made a joke about Smith’s wife, actor Jada Pinkett Smith.
This was likely the first time there had been real violence onstage at the ceremony

Chris Rock was on the Oscar stage to present the award for best documentary when he began by making a few jokes about members of the show’s audience, including Pinkett Smith—referring to her as “G.I. Jane” due to her closely cropped hair.
Shortly after the joke was made, Will Smith walked to the stage and slapped the comedian across the face. He then returned to his seat and shouted, “Keep my wife’s name out of your fucking mouth.”
Smith later won an award and he used his acceptance speech to apologise to the Academy. However, he did not apologise to Chris Rock.
