Fire Jugglers
From Tardis Wiki, the free Doctor Who reference
The Fire Jugglers were two jugglers who were part of the Night Travellers. When film and cinema killed off the travelling shows, the jugglers were trapped on film until the 21st century, when Pearl and the Ghostmaker freed them and the other Night Travellers. Jack Harkness then filmed them on a film camera and exposed the untreated film to sunlight, destroying them. However, Jack feared that the Night Travellers could return through other lost rolls of old film that contained them. (TV: From Out of the Rain)
