Cottingley fairy photos

Taken in 1917, the Cottingley fairy photos showed frolicking fairies. Though they were discredited as a fake later, no less than Sir Arthur Conan Doyle believed in them. One of the photos showed Jasmine Pierce, a formerly human Chosen One from 2007, now changed into a fairy herself. (TV: Small Worlds)

Behind the scenes
In reality, Sir Arthur Conan Doyle did believe in the authenticity of the photos, having accepted the existence of the supernatural by that time in his life.

One of the fairies in the photo shown in extreme close-up in Small Worlds and on the Torchwood website was retouched to make it appear to have Jasmine's face.

Soon after playing the Eighth Doctor in Doctor Who, Paul McGann starred in the 1997 film FairyTale: A True Story, another fictionalised account of the photos which portrayed them as genuine.
