Winston Zeddemore - Conception and Creation

Conception and Creation

In the original script for Ghostbusters, Winston Zeddemore was intended to be the smartest and most capable of the Ghostbusters, a former Marine with multiple degrees and a Ph.D., making him more suited for the job than the founding three Ghostbusters. However, in the final screenplay none of these qualifications were mentioned. The changes are discussed in detail in the commentary on the DVD of Ghostbusters, the explanation being Winston allowed the technobabble to be put into layman's terms.

However, the novelization of Ghostbusters mentions Zeddemore's service with the Marines prior to joining the Ghostbusters. Further, in Ghostbusters: The Video Game, while the Ghostbusters are on a mission in the New York History Museum, Zeddemore reminisces about the time he spent studying for his doctorate in the museum's Egyptology wing. (In context, it's unclear if Zeddemore studied for the doctorate prior to joining the Ghostbusters, or sometime between the events of the movies and the game's setting in 1991.)

Zeddemore is a religious man to some extent, saying in a discussion in Ghostbusters that he believes in God and "loves Jesus' style". While driving the Ecto-1 with Ray he voices his thoughts that the sudden spike in ghosts appearances might be a sign of the apocalypse.
