Film 900: Ghostbusters II

Trivia:  In the scene when Egon looks up information about Vigo in the database, Vigo's full name is listed as Vigo Von Homburg Deutschendorf. The actor who plays Vigo is Wilhelm von Homburg and the twins who play Oscar are William T. Deutschendorf and Henry J. Deutschendorf II. The twins are the nephews of singer John Denver whose real name was Henry J. Deutschendorf I.

The kid who tells Ray that, according to his dad, the Ghostbusters are "full of crap" is played by Jason Reitman, the son of director Ivan Reitman. Reitman's daughter Catherine Reitman plays the girl with the puppy in Egon's lab.

The cameo appearance of Slimer the green ghost of Ghostbusters was prompted by the fact that in the years in between the two films, the cartoon series The Real Ghost Busters introduced the idea that Slimer was living at the firehouse as the Ghostbusters' pet. Because the original film and the cartoon series were so popular with children, they put Slimer in the film.

In the courtroom scene, the prosecuting lawyer is carried out of the room upside-down by her leg by one of the ghosts. In the trailer, you see the prosecuting lawyer floating out of the room upside-down as the ghost SFX have not yet been added.

The pneumatic subway line that Ray finds when they lower him below the street was based on a pneumatic line built in 1870 by Alfred Beach. It operated using compressed air and was built as a demonstration of a pneumatic transit system. The one-block-long tunnel was built prior to any other subways in the area and without any City approval. It had a single beautifully appointed station adorned with frescoes, easy chairs, statues and a goldfish pond. The line was shut down in 1873 due to lack of official and financial support. The tunnel entrance was sealed and the station was reclaimed for other uses. In 1912, when digging for the modern subway system, workers found the original tunnel, still in good condition, and the remains of the passenger car. The tunnel was removed to make way for the contemporary subway lines and the passenger car has disappeared into history. Today there are no physical remains of Beach's experimental and ambitious subway project.

A scene where patrons run out of a movie theater as slime oozes from the area has Cannibal Girls with Eugene Levy and Andrea Martin showing on the marquee. "Cannibal Girls" was one of Ivan Reitman's first films as a director.

The psychiatrist at the mental hospital is played by Bill Murray's real life brother, Brian Doyle-Murray.

Janine's appearance was significantly different than in the first movie to coincide with the appearance of how she looked in the animated show, The Real Ghost Busters.

Bill Murray told Entertainment Weekly he was very disappointed with the way the film turned out. He commented "it was a whole lot of slime, and not much of us."
