Ghostbusters (1984)

Winston Zeddemore's first on-screen appearance is in the movie Ghostbusters, when he responds to a help-wanted advertisement the team has posted in an attempt to deal with their sizable workload.^[2] Questioned extensively during his application by Janine Melnitz as to whether he believes in a large number of supernatural occurrences and beings (such as UFOs, the Loch Ness Monster and the theory of Atlantis among others), Zeddemore replies, "If there's a steady paycheck in it, I'll believe anything you say." When Ray Stantz and Peter Venkman return from a call, Janine introduces Zeddemore to them and Stantz immediately hires him. In the film's novelization, it is stated that Zeddemore has recently been discharged from Strategic Air Command, and has moved in with his mother Lucille while he looks for work and an apartment. He is college-educated and had electronic countermeasures training. Further, Ray is impressed at Zeddemore's military backgrounds along with his proficiency in karate and firearms handling, after reviewing his resume. Despite not being a scientist, Zeddemore is highly intelligent and soon learns to operate the team's equipment. Later in the movie, having seen the level of paranormal activity present in the city, he remarks, "This job is definitely not worth eleven-five [$11,500] a year!" He is partnered with Stantz and they become friends, and they share responsibility on the maintenance of the team's Cadillac Ecto-1.

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 Stantz, he voices his thoughts that the sudden spike in ghost appearances might be a sign of the apocalypse, pointing out that while they have come to treat capturing ghosts as routine pest control, in a very real sense the dead are literally "rising from the grave", potentially an omen of the apocalypse.

Though Zeddemore has no previous background in paranormal studies and is not initially a firm believer in the existence of the paranormal, he readily accepts the existence of ghosts and the supernatural as he encounters them as a Ghostbuster. He also rises to the challenge and proves very skilled and dependable team member. However, he continues to act as an "everyman" and voice of reason for the team, and when the jailed Ghostbusters seriously propose asking a federal judge to release them because they must fight an invading god, Zeddemore reminds the others that no one will believe their claims. Despite this, when meeting with the Mayor of New York he offers himself as a somewhat impartial observer, due to only having joined the team recently, and assures the mayor that the phenomena are real.

Ghostbusters II (1989)

At the start of the sequel Ghostbusters II, the team has been forced out of business due to legal injunctions and property damage lawsuits. Zeddemore and Stantz work as unpopular children's entertainers, but rejoin the team after the ban against them is lifted. Winston later develops a dislike against Vigo the Carpathian after learning his atrocious past from Egon and Ray, calls him an "ugly dude" after seeing his portrait. He helps Stantz and Egon Spengler investigate a mysterious river of slime under the city and, in the process, revealed to have a fear of rodents before they encounter a number of specters that haunt the city's subway tunnels and then being "hit" by a phantom vehicle of a train that derailed in the 1920s. Later, he helps them pilot the Statue of Liberty (suffused with slime charged by positive emotions) through New York City to rally the public and defeat the spirit of Vigo the Carpathian. Ray remarks that the slime reminds him of Jell-O, a dessert Winston hates.

Ghostbusters: Afterlife (2021)

Hudson reprised his role as Zeddemore in Ghostbusters: Afterlife (2021).^[7] In the years since the Ghostbusters business collapsed, Winston has started a successful global enterprise, crediting his time as a Ghostbuster as his inspiration to start it. Despite his successes, Winston remains loyal to his friends and still thinks fondly of being a Ghostbuster, ready to return to action. It is also revealed that he is married, and it is stated by Winston that his children are aware that he was a Ghostbuster. In the final act of the film, he arrives with Venkman and Ray to help the Spengler family deal with a returned Gozer. At the end of the film, being sentimental of his past, Winston buys the team's old firehouse headquarters back from Starbucks, and has the Ecto-1 restored and delivered there. Janine Melnitz knows that he has been paying the rent on Ray's occult bookstore for some time, as a way of honoring their friendship.

The Real Ghostbusters

Many details of Zeddemore's personality and character are revealed in episodes of The Real Ghostbusters. The episode "Cry Uncle" clarifies that, in the show's continuity, Winston has no doctorate; he also informs Egon's skeptical Uncle Cyrus that, prior to becoming a Ghostbuster, he too doubted the existence of ghosts. In "Mr. Sandman, Dream Me a Dream," Winston states that, unlike his three colleagues, he is not a scientist, causing him to doubt his ability to resolve a crisis when the Sandman traps the others within their own dreams, but with encouragement from a dream-version of Albert Einstein, he meets the challenge and wins the day. "The Ghostbusters in Paris" reveals that Winston was once a construction worker prior to joining the Ghostbusters. This idea seems to be further reinforced in the episode "The Brooklyn Triangle", when the Ghostbusters respond to a construction site headed by his father; this would indicate that it might have been a family business, until Winston decided to join the Ghostbusters.

In the episode "Devil To Pay", Zeddemore mentions having a girlfriend, though she is never seen on screen during the series. In "Night Game", he is shown to love baseball, and his favorite team is the Jaguars. In several other episodes it is shown that Zeddemore loves mystery novels and detective stories, and in "Boodunnit" he is the one who solves the mystery novel left behind by a deceased mystery writer similar to Agatha Christie, allowing her soul to rest. In "Doctor, Doctor" it is revealed that Zeddemore also likes classical literature, including the works of Herman Melville and Charles Dickens. He is also a fan of The Alan Parsons Project. "The Brooklyn Triangle" introduces Winston's father, Ed, who works in construction. Their relationship is shown to have been strained because of Winston choosing to be a Ghostbuster, but they reconcile by the end of the episode.

Finally, in the episode "The Moaning Stones", Zeddemore is revealed to be the reincarnation of Shima Buku, a shaman at war with an immortal demon known only as the Undying One.

On his one day off, Winston went to go see a performance of the Aida opera. However, the Psi Energy Pulse officially cancelled his plans. After Janine delivered the message, Winston left to meet up with the other Ghostbusters at the Sedgewick Hotel. He endured four hours of traffic but made it to the hotel just in time to see the Stay Puft Marshmallow Man. During their final confrontation, Ivo Shandor mocks Winston, saying that he always thought Winston was the "slow" one of the group, much to Winston's surprise.
