The Academy Awards briefly came to a stunning halt Sunday night when Chris Rock made a joke about Jada Pinkett Smith, after which Will Smith went to the stage and hit him in the face.

The moment was not planned, said a person close to the Oscars production….Smith, who played Richard Williams (the father of tennis prodigies Venus and Serena) in the biopic “King Richard,” appeared onstage about 40 minutes later to accept his prize for best actor.
