A legendary,excellent actor. His films were groundbreaking. I remember being in the musical adaptation of A Raisin in the Sun in high school. One of my favorite (among many) of Poitier's films. May he rest in paradise,as Sutton said.
I had the opportunity to meet him briefly on a film I worked on, that he produced. He was just as gracious and considerate as you might imagine. One of the high points of my film work.
