Ghostbusting Titanic

The picture below is a screenshot from the 1989 sequel of the famous 1984 film Ghostbusters: Ghostbusters II. In this film, shortly before the soul of the Moldovan tyrant Vigo the Carpathian takes power by exiting from the painting where it was trapped, many people called the NYPD after seeing ghosts in Manhattan, where the Ghostbusters Peter Venkman, "Ray" Stantz, Egon Spengler, Winston Zeddemore and their friends Janine Melnitz, Louis Tully and Dana Barrett lived.
One of thes ghosts is the ghost of the wreck of the famed British ship RMS Titanic, that appears in a gag scene during Chapter 21 of Ghostbusters II.
The Royal Mail Ship Titanic was a White Star Line Olympic-class ocean liner launched on May, 31, 1911; that sunk on April, 14, 1912 after the collision with an iceberg and was found underwater in 1985, four years before the release of the film, but the Industrial Light & Magic model used in the film is clearly different from the real ship wreckage and any other ship that sunk after the collision with an iceberg!
