8 Sci-Fi Movies That Re-Used Props From Other Movies

The Ghostbusters are well-known for their massive array of iconic gadgetry: their proton packs, ghost traps, Ecto-1, containment unit and of course the P. K. E. Meter. Designed by jargon-spewing boffin Egon Spengler, the device was used to track ghosts by reading for signs of Psycho-Kinetic Energy - whatever that means - and when those two prongs shot out, it was a sign that sh*t was going to get real intense, real fast.

The gadget then shows up again in John Carpenter's 1988 sci-fi satire They Live, another darkly comic film featuring humanity at risk from an unseen entity - though this time far more insidious and sinister. Near the end of the film, as Rowdy Roddy Piper and Keith David begin shooting their way through a newsroom, the P. K. E. Meter can be seen being used as some kind of all-round tracking and communication device by the alien military.

Unlike previous entries, there doesn't appear to have been any redesigning work done on the device at all - it looks and seemingly functions identically to Ghostbusters' original design. Come on, production designers, at least change the colour of the prongs' LEDs or something.
