Behind the scenes

• During the Army of Ghosts scene, the musical soundtrack subtly references the Ghostbusters theme.
• 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. Also, the buster's vehicles siren shared the same alarm sound used in the television story The Waters of Mars.
• Ernie Hudson was one of the stars of the 1984 film and its 1989 sequel Ghostbusters II.
• Most references are to the original 1984 film. In 2016, a rebooted version of the film was released with all-female cast, which included Kate McKinnon playing Dr Jillian Holtzmann.
• A toy of the character Stay Puft is seen in Craig Owens' flat in TV: The Lodger.
• The franchise appeared alongside Doctor Who in LEGO Dimensions.
• A Ghostbusters comic book series was published by IDW Publishing.
