Ghostbusters

"Ghostbusters" was a comedy film from 1984 about an organisation that fought ghosts.

When investigating the Ghost Shifts, the Doctor referenced the theme song when he brought out a device to track them, asking Rose "who you gonna call?", to which she replied "Ghostbusters!" (DW: Army of Ghosts)

In Ashen Hill Manor, Clyde Langer wished he had a Proton Pack from the movie when trying to find a ghostly entity. He also said "I ain't afraid of no ghost", part of the Ghostbusters' theme tune. (SJA: The Eternity Trap)

In part two of Death of the Doctor the sound effect used during the activation of the Memory Weave is the same sound effect used in the Ghostbusters movies, cartoons, and video games for powering up a Proton Pack.(SJA: Death of the Doctor)
