Obviously, Sidney Poitier's lengthy career has much more cultural significance than how much he earned for his work — but his net worth is pretty impressive. Since he was one of the last surviving actors of the Golden Age of Hollywood, it's understandable that he hasn't starred in any major fiction projects since 1997's "The Jackal" and 2001's "The Last Brickmaker in America" (via IMDb). However, according to CelebrityNetWorth.com, Sidney Poitier was worth $20 million at the time of his death.
Most audiences aren't going to remember Sidney Poitier for his net worth — instead, he'll be remembered for the cultural impact he had in the 1960s and 1970s, as well as his performances as Virgil Tibbs in "In the Heat of the Night," "They Call Me Mister Tibbs!," and "The Organization." Poitier paved the way for an entire generation of actors, and he'll be missed by many.
