At the top of his game: Sidney Poitier on the set of For Love of Ivy, New York City 1968-I photographed Sidney performing in Ivy, a movie he also wrote. This same year, he starred in three box office hits: Guess Who's Comming to Dinner, In the Heat of the Night and To Sir With Love. Sidney Poitier did for the movies what Jackie Robinson did for Baseball. Not only could they play with the best, they were the best. And they made sure that the doors they opened stayed open.
