Winston Zeddemore is one of the original Ghostbusters. The original movie role was played by Ernie Hudson. The movie spawnned two animated cartoon series and he was in both of them. Winston was a full-fledged member of the original team but while he participated fully in most of the ghostbusting activities, due to his lack of comparable education to the other members, he was
often relegated to the role of driver and mechanic. He tended to be the 'every-man' character' and often the voice of reason.
The first cartoon series, The Real Ghostbusters, lasted 8 seasons. During the first 3 seasons, Winston was voiced by Arsenio Hall. During seasons 4 through 7, he was voiced by Buster Jones. The Extreme Ghostbusters series lasted only one season. The character of Winston was voiced, once again, by Buster Jones. In Ghostbusters the video game, the character was voiced by the actor who originally played him in the movie, Ernie Hudson. There have also been multiple action figures made and sold in the Winston's likeness.
Believe it or not, in the original script for the Movie, Winston Zeddemore was supposed to be smarter and more capable that the other Ghostbusters with multiple degrees and a stint in the Marines. Too bad it didn't turn out that way in the final presentation.
